Using "return" in Async Google Cloud Functions

I am somewhat new to coding and recently created this script in order to pull data from Zoom and push it to Google Drive via API. I am trying to push this to a Google Cloud Function, but when running it in a Cloud Function and console logging each step in the process, it seems like the uploadFile function, specifically the drive.files.create method, is being skipped. Every other step is being console logged, but neither the err or res is being logged after the drive.files.create method. Google Cloud Functions does not show errors, instead it shows OK and that the function took 1500ms to execute. It works fine on my local machine, I am only having issues in Cloud Functions. Any suggestions on how to get this to act right would be super helpful. Thank you!

As you are calling an API inside a cloud function which is an async function but does not have a return statement, it will only execute the function but doesn't wait for the response, because the drive.files.create call is running.
So to fix that just need to await the result of the API. Just add
return await statement on the API call
like:
const uploadFile = async (auth) => {
const buffer = await zoomDownloadLink();
const bs = new stream.PassThrough();
request(buffer).pipe(bs);
const drive = google.drive({ version: "v3", auth });
var fileMetadata = {
name: `${today.substring(0, 4)}.${today.substring(5, 7)}.${today.substring(8,10)} - Town Hall.mp4`,
parents: ["XXXXXXXXXXXXXXXXX"],
};
var media = {
mimeType: "video/mp4",
body: bs,
};
return await drive.files.create(
{
resource: fileMetadata,
media: media,
fields: "id",
uploadType: "resumable",
supportsAllDrives: true,
},
function (err, res) {
if (err) {
console.log(err);
} else {
console.log("File Id: ", res.data.id);
}
}
);
};
Also, something important when you are calling APIs inside cloud functions is the time out. Check on your CF time out is enough to wait for the API call response.
Also, you can use the Promise function to force wait for the response:
const result = uploadFile(aut);
const _response = await Promise.all(result);

I am using metamask as wellet for bidding
Hi, I am using above code to place bid on opensea It is working but, I am using my personal MNEMONIC
But, in real time i can't get this from users meta mask wallet.
Is there any alternate way to place the bid.

Can "ERROR Unhandled Promise Rejection" be a problem in aws lambda?

Can this anyhow in the feature damage the flow they belong to?
I have a lambda that works behind a API Gateway websocket endpoint.
This simply asks for a clientId and a message payload, query all connections on dynamo for that clientId (multi device realtime dashboard frontend) and updates all interested users.
It's working fine if you test trought "wscat" on command line but it is buggy on real world browser using js websocket api or c# websocket api.
Doest this exceptin has anything to do with it?

I think problem is with API Gateway, check how you are handling information passing through to Lambda function (because browser sends some extra information as compared to command line call)

Returning Output from AWS.DynamoDB.DocumentClient.Scan() Call

I've got a function that returns the number of records from a DynamoDB table (Things):
const table = 'Things';
const region = 'us-east-1';
const profile = 'development';
process.env.AWS_SDK_LOAD_CONFIG = true;
process.env.AWS_PROFILE = profile;
const AWS = require('aws-sdk');
AWS.config.update({ region: region });
function ddb_table_has_records(table_name) {
const ddb_client = new AWS.DynamoDB.DocumentClient();
const ddb_query_parameters = {
TableName: table_name,
Select: 'COUNT'
}
const results = ddb_client.scan(ddb_query_parameters).promise();
results.then((data) => {
console.log(data.Count);
return data;
}).catch((err) => {
console.log("Error: ", err);
})
}
console.log(ddb_table_has_records(table));
When I run this code, I get the following...
PS C:\> node .\get-count-thing.js
undefined
3951
I'm not capturing the data from the scan in the following; although, I see it in the console.log() call:
console.log(ddb_table_has_records(table));
What am I mucking up?

Posting my fix in-case anyone has the same question. I had to make two changes to retrieve the items from the table; I needed to...
...project ALL_ATTRIBUTES
...iterate over the collection of Items returned
The following was my function with changes:
function ddb_table_has_records(table_name) {
const ddb_client = new AWS.DynamoDB.DocumentClient();
const ddb_query_parameters = {
TableName: table_name,
Select: 'ALL_ATTRIBUTES'
}
const results = ddb_client.scan(ddb_query_parameters).promise();
results.then((data) => {
console.log(data.Count);
data.Items.forEach((thing) => {
console.log(thing);
});
}).catch((err) => {
console.log("Error: ", err);
})
}

Can't figure out why my app.get is being run twice?

I have a app.get which inside of it is quite a bit of logic. Which everything works great aside from some of the logic being called twice for some reason. I have noticed when I was saving something to by db that it would save two rows.
So I put a console.log in that area and sure enough it was logging it twice.
Any reason why this is happening?
app.get('/shopify/callback', (req, res) => {
const { shop, hmac, code, state } = req.query;
const stateCookie = cookie.parse(req.headers.cookie).state;
if (state !== stateCookie) {
return res.status(403).send('Request origin cannot be verified');
}
if (shop && hmac && code) {
// DONE: Validate request is from Shopify
const map = Object.assign({}, req.query);
delete map['signature'];
delete map['hmac'];
const message = querystring.stringify(map);
const providedHmac = Buffer.from(hmac, 'utf-8');
const generatedHash = Buffer.from(
crypto
.createHmac('sha256', config.oauth.client_secret)
.update(message)
.digest('hex'),
'utf-8'
);
let hashEquals = false;
try {
hashEquals = crypto.timingSafeEqual(generatedHash, providedHmac)
} catch (e) {
hashEquals = false;
};
if (!hashEquals) {
return res.status(400).send('HMAC validation failed');
}

const accessTokenRequestUrl = 'https://' + shop + '/admin/oauth/access_token';
