Store log and send it to slack

I need to store errors in the logs table. If I understood correctly, I should write a report for this in Handler.ts
This is my Handlet.ts
export default class ExceptionHandler extends HttpExceptionHandler {
constructor() {
super(Logger)
}
public async handle(error: any, ctx: HttpContextContract) {
console.log(error.messages)
await Log.create({
type: 'menus.store', // if we get error in menu store function
message: error.messages,
})
return super.handle(error, ctx)
}
}
I have two problems. how can I know in which method error I get? to add it to type in log creation.
The second question is that I get the same error that am getting in insomnia when testing. for example:
{"errors":[{"rule":"number","field":"menuId","message":"number validation failed on menuId"},{"rule":"exists","field":"menuId","message":"exists validation failed on menuId"}]}
But I need a full error, I'm getting full error in the visual studio terminal.
How can I add this error to the Log message?

How can I log this error?

MongoServerError: Nested BSON depth greater than 50 not allowed

I want to update an object key from mongodb. But when i want to update that key, I am getting this error

Node Js and Ebay api

I am novice to NodeJs and working with ebay-api.
I found this great example at GitHub
one strange issue is when I run the js file via CMD. it is working but sometimes it shows error and then I cleared cache it works and sometimes after clearing the cache it shows error. But the code is exactly the same which I got output correctly. Did anyone face the same issue or any idea where might be the problem?
var ebay = require('../index.js');
var params = {
keywords: ["Canon", "Powershot"],
// add additional fields
outputSelector: ['AspectHistogram'],
paginationInput: {
entriesPerPage: 10
},
itemFilter: [
{name: 'FreeShippingOnly', value: true},
{name: 'MaxPrice', value: '150'}
],
domainFilter: [
{name: 'domainName', value: 'Digital_Cameras'}
]
};
ebay.xmlRequest({
serviceName: 'Finding',
opType: 'findItemsByKeywords',
appId: '<your app id>', // FILL IN YOUR OWN APP KEY
params: params,
parser: ebay.parseResponseJson // (default)
},
// gets all the items together in a merged array
function itemsCallback(error, itemsResponse) {
if (error) throw error;
var items = itemsResponse.searchResult.item;
console.log('Found', items.length, 'items');
for (var i = 0; i < items.length; i++) {
console.log('- ' + items[i].title);
console.log('- ' + items[i].galleryURL);
console.log('- ' + items[i].viewItemURL);
}
}
);
I'm getting the following errors:
C:\node_modules\ebay-api\examples> node H:\NodeJs\app.js //Run via NodeJS CMD
H:\NodeJs\app.js:36
if (error) throw error;
^

Your suggestions would be appreciated. Thanks

You can use this node module ebay-node-api where you can get the response data in form of JSON.
You can check this example to check how to consume ebay-node-api
https://github.com/pajaydev/ebay-node-api/

You are throwing an error object in the callback but you are not catching it anywhere in the code. Please handle the error you are throwing.

MongoDB oplog stream Node.js

I have a local instance of MongoDB, started with --master, and I can see in the start log that I have a replica set oplog (file: /data/db/local.1) created. And it appears local.1 is updated every time I perform and insert().
I am trying to tail / stream the oplog with the following code...
MongoDB.connect('mongodb://localhost:27017/test',(e,db) => {
if ( e ) { return console.log('Connect MongoDB Error',e); }
console.log('Connected MongoDB');
Server.DB = db;
db.collection('oplog.rs').find({}).toArray((e,d) => {
console.log('oplog.rs');
console.log(e);
console.log(d);
})
var updates = db.collection('oplog.rs').find({},{
tailable: true,
awaitData: true,
noCursorTimeout: true,
oplogReplay: true,
numberOfRetries: Number.MAX_VALUE
}).stream();
updates.on('data',(data) => { console.log('data',data); });
updates.on('error',(e) => { console.log('error',e); });
updates.on('end',(end) => { console.log('end',end); });
});
The Code logs the following on start...
oplog.rs
null
[]
However there is no output from stream, I set numberOfRetries to a lower value I get the error..

oplog.rs is used in replica sets. Starting mongodb with --master you are using long-deprecated master-slave replication, which uses local.oplog.$main database, so there is nothings in oplog.rs.
You need to start mongod with --replSet to benefit from replica set oplog. Read more how to deploy and configure replica sets.

Sequelize TypeError: Cannot read property '1' of null

Normally this type of error would not be a problem but i simply cannot understand where this is happening:
Here is my setup:
router.route('/api/academyModule')
.post(function (req, res) {
req.body.academyModule.module_id = req.body.academyModule.module.id;
req.body.academyModule.module_module_type_id = req.body.academyModule.module.module_type.id;
var am = AcademyModule.build(req.body.academyModule);
am.add(req.body.academyModule.requirements, req.body.academyModule, function (success) {
res.json({id: this[null]});
},
function (err) {
res.status(err).send(err);
});
if(req.body.teams != null)
{
req.body.teams.forEach(function(y)
{
var atm = academy_team_has_academy_module.build({academy_team_id: y.id, academy_id: y.academy_id, academy_module_module_id: req.body.academyModule.module_id })
atm.add(function(success)
{
}, function(err)
{
res.status(err).send(err);
});
});
}
})
For this i have the following model:
academy_team_has_academy_module = sequelize.define('academy_team_has_academy_module', {
academy_team_id: {
type: DataTypes.INTEGER,
primaryKey: true,
autoIncrement: false
},
academy_id: DataTypes.INTEGER,
academy_module_module_id: DataTypes.INTEGER
}, {
freezeTableName: true,
instanceMethods: {
add: function (onSuccess, onError) {
academy_team_has_academy_module.build(this.dataValues)
.save().ok(onSuccess).error(onError);
}
}
});
i know for sure this happens in this model and not AcademyModule because when i remove this code it runs without any issues. So in my console i get the following print out:
Executing (default): INSERT INTO `requirements` (`id`,`value`,`requirement_type_id`) VALUES (DEFAULT,5,'2');
Executing (default): INSERT INTO `academy_team_has_academy_module` (`academy_team_id`,`academy_id`,`academy_module_module_id`) VALUES (1,3,11);
Executing (default): INSERT INTO `academy_module` (`academy_id`,`module_id`,`module_module_type_id`,`sort_number`,`requirements_id`) VALUES ('3',11,4,4,40);
And just right after i get:
/var/www/learningbankapi/src/node_modules/mysql/lib/protocol/Parser.js:82
throw err;
^

Ive debugged the whole thing and i can't seem to find any undefined variables. What might have gone wrong here?

Your problem is a ForeignKeyContraintError. Sequelize is trying to throw a new error but get's an unexpected error.message. If your configuration is fine, this may be an bug of sequelize.
Maybe deactivating foreign contraint checks (if possible) will solve your problem.
See: https://github.com/sequelize/sequelize/blob/master/lib/dialects/mysql/query.js#L153
