JavaScript Invalid export data. Please provide an array of objects

Im writing a function to export data pulled from C# to a csv file in JavaScript. The data is trying to be passed into an active webpage with live data. The goal is to export said data from C# string to the clients window hence the transfer to JavaScript (if my understanding is right). Then the JavaScript function in the page will download to the users window.
My issue is why am I have the invalid export data, please provide an array of objects output when I think I provide it one?
C# Code:
protected string test()
{
MyRequest request = new MyRequest();
request.Id = "TEST";
// Cant post this class but this is what I do
var tmp = new ExistingClassOfMine();
// pulls the data from the existing class through GetResponse();
// Then convert to json string
string data = JsonConvert.SerializeObject(tmp.GetResponse(request));
// Data found from breakpoint: {"Slot1":[{"Name":"TJ", "ID":"123"},{"Name":"Joe","ID:456"}], "TotalCount":2}
return data;
}
JavaScript:
function exportToExcel() {
console.log("Exporting to Excel");
isExporting = true;
const fileName = 'NameList';
const exportType = 'csv';
var data = <%=this.test()%>;
var readData = data["Slot1"];
var myArray = [];
// Followed a stack article to create this
for (var i in readData) {
myArray.push(readData[i]);
}
// Logging stuff for debugging
console.log("Data from C#");
console.log(data);
console.log(typeof (data));
console.log("Data we want to export");
console.log(readData);
console.log("Parsed Data?");
console.log(myArray);
// fails here with the error Invalid export data, please provide an array of objects
// which I thought I did with my for loop up a few lines
window.exportFromJSON({myArray, fileName, exportType});
isExporting = false;
}
function onRequestStart(sender, args) {
if (isExporting) {
args.set_enableAjax(false);
}
}
Log output:

Look, your triying to change the name of the key which is sent to exportFromJSON. The right way to name the key is data no myArray.
Change:
myArray
to
data
or assign myArray to data key
window.exportFromJSON({data:myArray, fileName, exportType});

retrieving data from database according to query conditions

"_id":{"$id":"61b5eb36029b48135465e766"},
"name":"push-ups","link":"https://google.com",
"image":"https://google.com",
"gender":["0","1","2"],
"goal":["lw","gw","sf"],
"age":60,
"excersietype":"chest",
"__v":0
this is how my data is stored in database
and I want to fetch data according to 3 condition
I got 3 queries from front gender goal and age and according to that I have to retrieve data
const gender = req.query.gender;
const age = req.query.age;
const goal = req.query.goal
const level = req.query.level
if (level==='fb'){
const getdata = new Forbeg.find({gender:{$in:gender}},{age:{$lte:age}},{goal:{$in:goal}});
console.log(getdata)
}
Is this a good way to find the data because I am getting error
UnhandledPromiseRejectionWarning: MongooseError: `Model.find()` cannot run without a model as `this`. Make sure you are not calling `new Model.find()`
I am getting above error while fetching

The error is explicit : Make sure you are not calling 'new Model.find()'. Use const getdata = Forbeg.find(...).
However, you will immediately run into the next problem, as Mongoose models return thenables (Promise-like). console.log(getdata) will log Promise<pending>. You need to resolve your database call, either by doing
Forbeg.find(...).then( getdata => console.log(getData));
or (much more better!):
const getdata = await Forbeg.find(...);
console.log(getdata)
Even better, add .lean() to get simple JSON data instead of an array of Mongoose objects (faster), and .exec() to get a true Promise instead of a thenable :
const getdata = await Forbeg.find(...).lean().exec();
console.log(getdata)

Remove new operator
const getData = Forbeg.find({gender:{$in:gender}},{age:{$lte:age}},{goal:{$in:goal}});

Async Storage retrieve value of key in item

I'm new to Javascript and react native, and the question itself will be probably very easy to answer.
I'm setting up a AsyncStorage and creating a Item inside the storage, which is a .JSON that has 3 key values to it.
const saveDataToStorage = (token, userId, expirationDate) => {
AsyncStorage.setItem('userData', JSON.stringify({
token: token,
userId: userId,
expiryDate: expirationDate.toISOString()
}))
};
What I want to do now is to retrieve the "userId" value from this item in an other part of the project but here is the problem.
var PersonalId = await AsyncStorage.getItem('userData');
console.log(PersonalId);
console.log(typeof PersonalId);
I know how to access the item itself, but I have no clue how to access the special key inside it. I can not use the command:
var PersonalId = await AsyncStorage.getItem('userData').userId;
because the item from the AsyncStorage is a string, I know this because I got this info from the second line of my code.
console.log(typeof PersonalId);
How can I access the special key "userId" inside my item "userData" and not the whole item itself? I cant work with the item anyways because its a string, I can not treat it as an object and thats my problem.
Thank you for reading and helping out!

You need to first parse value you are getting from the AsyncStorage into a JSON object using JSON.parse(). Try this implementation.
const get_data = async () => {
const userData = await AsyncStorage.getItem("userData");
const userObject = userData !== null ? JSON.parse(userData) : {};
const personalId = userObject.userId;
console.log(personalId);
};

You are forgetting that you stringified the JSON before saving it to storage.. so you are getting string when you read it. Simply JSON.parse the returned string and you should be on your way.
const userData = await AsyncStorage.getItem('userData');
const personalId = JSON.parse(userData).userId;
You should also wrap the above code in a try-catch to make sure you catch errors when invalid data is tried to be parsed and it throws an error.

JS/NodeJS/VSCode - How to step into a console logged object [duplicate]

In the below code (running on Node JS) I am trying to print an object obtained from an external API using JSON.stringify which results in an error:
TypeError: Converting circular structure to JSON
I have looked at the questions on this topic, but none could help. Could some one please suggest:
a) How I could obtain country value from the res object ?
b) How I could print the entire object itself ?
http.get('http://ip-api.com/json', (res) => {
console.log(`Got response: ${res.statusCode}`);
console.log(res.country) // *** Results in Undefined
console.log(JSON.stringify(res)); // *** Resulting in a TypeError: Converting circular structure to JSON
res.resume();
}).on('error', (e) => {
console.log(`Got error: ${e.message}`);
});

Basic console.log will not go through long and complex object, and may decide to just print [Object] instead.
A good way to prevent that in node.js is to use util.inspect:
'use strict';
const util = require('util'),
obj = /*Long and complex object*/;
console.log(util.inspect(obj, {depth: null}));
//depth: null tell util.inspect to open everything until it get to a circular reference, the result can be quite long however.
EDIT: In a pinch (in the REPL for example), a second option is JSON.stringify. No need to require it, but it will break on circular reference instead of printing the fact there is a reference.

Print the whole object, it will not have problems with recursive refferences:
console.log(res);
Here's an example for you to see how console.log handles circular refferences:
> var q = {a:0, b:0}
> q.b = q
> console.log(q)
{ a: 0, b: [Circular] }
Also, I would advise to check what data are you actually receiving.

By using the http request client, I am able to print the JSON object as well as print the country value. Below is my updated code.
var request = require('request');
request('http://ip-api.com/json', function (error, response, body) {
if (!error && response.statusCode == 200) {
console.log(response.body); // Prints the JSON object
var object = JSON.parse(body);
console.log(object['country']) // Prints the country value from the JSON object
}
});

This can print the key of the object and the value of the object in the simplest way. Just try it.
const jsonObj = {
a: 'somestring',
b: 42,
c: false
};
Array.from(Object.keys(jsonObj)).forEach(function(key){
console.log(key + ":" + jsonObj[key]);
});

In 2021, I just printed using
app.post("/",(req,res) => {
console.log("HI "+JSON.stringify(req.body));
res.send("Hi")
});
and got my output as HI {"Hi":"Hi"}.
I sent
{
"Hi": "Hi"
}
as my post request body.
Only doing console.log(req.body) printed [object Object] on console but now this works.

Use console.dir and set the depth.
console.dir(obj, { depth:10 })
Alternatively you can set the default depth to change the console.log depth.
require('util').inspect.defaultOptions.depth = 10
All of this and details about this can be found in nodejs training.
https://nodejs.dev/learn/how-to-log-an-object-in-nodejs

You do not actually get data in res. You need on('data') and on.('end')
body is a string. It gets append on data received, so on complete you will need to parse data into json
http.get("http://ip-api.com/json", function(res) {
var body = '';
res.on('data', function(data){
body = body + data;
});
res.on('end', function() {
var parsed = {};
try{
parsed = JSON.parse(body); // i have checked its working correctly
}
catch(er){
//do nothing it is already json
}
console.log(parsed.country);
});
});
Noe from parsed which is a json object, you can get any property

You can pass two arguments to console.log()
Try this code after installing "yargs" And it will print whole object
console.log('object is' , yargs.argv);
I think may be it will help you to print whole object :)

how to access json data os asyncStorage function

I am using AsyncStorage to store data. Here is my function of storing data :
const profile = { userId, name, email };
await AsyncStorage.setItem('userProf', JSON.stringify(profile));
I have a problem when I try to access the data , if I console.log:
async componentWillMount(){
const profile = await AsyncStorage.getItem('userProf');
console.log(profile);
}
{"userId":"jefla3E0tjcJHhHKJK45QoIinB2","name":"egfgege","email":"ergeg#egrge.com"}
Now if I am willing to get only email value , I have tried with:
console.log(profile.email);
console.log(profile[0].email);
None of them worked, I get undefined as output, could you please help.

As AsyncStorage take and returns a string you will need to parse the string into json. You're already using JSON.stringify to save your object, you need to do the reverse operation to get it back to being an object.
const savedProfile = await AsyncStorage.getItem('userProf');
const profile = JSON.parse(savedProfile);
Then you should be able to access it the properties as you normally would, for example
const userId = profile.userId;
const email = profile.email;
const name = profile.name;
You may want to make sure that you perform a check that the returned value from AsyncStorage isn't null, as that will cause problems for you. Also await functions can throw, so you should make sure that you wrap your call to AsyncStorage in a try/catch
async componentWillMount(){
try {
const savedProfile = await AsyncStorage.getItem('userProf');
// you should check that the savedProfile is not null here
const profile = JSON.parse(savedProfile);
const userId = profile.userId;
const email = profile.email;
const name = profile.name;
} catch (err) {
console.warn(err);
}
console.log(profile);
}

When storing the value with AsyncStorage.setItem( ... ), you use JSON.stringify to convert the complete object into a String. This means, if you want to have a "normal" Object back (to use the dot operator), you have to use JSON.parse:
const profile = await AsyncStorage.getItem('userProf');
console.log(JSON.parse(profile));
