Error while sending message (whatsapp-web.js)

I am trying to send a message by using whatsapp web.js I dont know why I am facing the error.
app.post("/send",(req,res)=>{
const numbersBox = req.body.mobiles;
const numbers = numbersBox.split(",")
// loop through all the numbers and send message to each number.
numbers.forEach(async eachNumber=>{
const sanitized_number = eachNumber.toString().replace(/[- )(]/g, ""); // remove unnecessary chars from the number
const final_number = `91${sanitized_number.substring(sanitized_number.length - 10)}`; // add 91(india code) before the number
const number_details = await client.getNumberId(final_number); // get mobile number details
if (number_details) {
const sendMessageData = await client.sendMessage(final_number, req.body.message); // send message
} else {
console.log(final_number, "Mobile number is not registered");
}
})
})
When I tried to send messages without using forEach loop and sending message to single user it got succeeded but now it is showing below error
throw new Error('Evaluation failed: ' + helper_js_1.helper.getExceptionMessage(exceptionDetails));
^

are you adding the "#c.us" at the end of the numbers? Every contact id should be like "5958978454#c.us" to consider it a valid number

Uncaught (in promise) SyntaxError: Unexpected token N in JSON at position 0

I have made a small vanilla javascript code to fetch api but it is throwing the error "Uncaught (in promise) SyntaxError: Unexpected token N in JSON at position 0". I m not able to understand, exactly why the error is caught. Can somebody help me to resolve this.
const config = {
url: "https://randomuser.me/",
numberCards: 24
};
fetch(`${config.url}&amount=${config.numberCards}`)
.then(function(response) {
return response.json();
})
.then(function(apiResponse) {
// Output API response to console to view.
console.log(apiResponse);
});

It's because of this.
const config = {
url: "https://randomuser.me/",
numberCards: 24
};
fetch(`${config.url}&amount=${config.numberCards}`)
It should be,
const config = {
url: "https://randomuser.me/api/",
numberCards: 24
};
fetch(`${config.url}?amount=${config.numberCards}`)
It's because the json data are from "https://randomuser.me/api/". Not "https://randomuser.me/". And the query strings must begin with a "?" mark. "&" mark is used to separate query strings. (like this "https://example.com/?amount=24&hi=en")

SyntaxError: Unexpected token v in JSON at position 2

I am running a node.js server running express.js on my local machine and need to decode a request made by the client, that contains a json string in it. I run the code below and get the following error.
SyntaxError: Unexpected token v in JSON at position 2
at JSON.parse (<anonymous>)
at C:\myLocation\source\repos\server\server\server.js:144:19
at Layer.handle [as handle_request] (C:\myLocation\source\repos\server\server\node_modules\express\lib\router\layer.js:95:5)
at trim_prefix (C:\myLocation\source\repos\server\server\node_modules\express\lib\router\index.js:317:13)
My request is
http://localhost:1337/%7B%22Code%22:%22VNdVwY9iWhFZ114CjcDZbY%22,%22Chat%22:%22Test.txt%22%7D
The expected json is
{"Code":"VNdVwY9iWhFZ114CjcDZbY","Chat":"Test.txt"}
I get the json, but it still gives me the same error.
My code:
app.use(function (req, res) {
//console.log(req.url)
var myStr = req.url.replace('/', '')
if (myStr != false) {
let decodeStr = decodeURIComponent(myStr)
var test = JSON.parse(decodeStr)
var json = JSON.stringify(test)
if (json.includes(createkey)) {
console.log("Create: " + json)
createFile(req, res, test)
} else if (json.includes(modKey)) {
console.log("Modify: " + json)
modifyFile(req, res, test)
} else if (json.includes(readFileKey)) {
console.log("Read: " + json)
readFile(req, res, test)
}
} else {
res.sendStatus(404)
console.log("home")
}
})
Why do I get the error?
Edit 1
I added console.log(decodeStr)but I still get the error. It returns {"Code":"VNdVwY9iWhFZ114CjcDZbY","Chat":"Test.txt"}

{"Code":"'GAHGAaphgAP:gjpaGHAHAG{AaGRAP;GHPG;RA","Chat":"Test.txt"} is not a valid json, that's why you encounter that error,
The other way around, you could parse
JSON.parse('{"Code":"\'GAHGAaphgAP:gjpaGHAHAG{AaGRAP;GHPG;RA","Chat":"Test.txt"}')
Try
var uri = "http://localhost:1337/%7B%22Code%22:%22%5C'GAHGAaphgAP:gjpaGHAHAG%7BAaGRAP;GHPG;RA%22,%22Chat%22:%22Test.txt%22%7D";

Why is my (try-catch) code executed too soon in NodeJS?

On the response of an HTTP GET call (with native http module), I try toJSON.parse() the response after the end event is emitted. I know for sure the the data i'm getting is valid JSON but still the JSON.parse throw an error. And my logs indicate that the JSON.parse is invoked before it should.
res.on("end", () => {
console.log('Req ended message is', body);
try {
var passport = JSON.parse(body);
} catch (e) {
w.info(
"Cannot parse the response from : " +
process.env.mongo_api_host +
" | error : " +
e
);
}
callback(passport);
return;
});
And my log shows :
info: Getting MongoDB passport for model : CESI
info: Cannot parse the response from : mongo_api | error : SyntaxError: Unexpected end of JSON input
info: Req ended message is *long valid JSON data*
We can clearly see in the logs that the parse error is caught and logged before the "Req ended message is : ... stuff".
What am I missing ?
Edit 1 :
Even by putting callback(passport) inside try block as suggested in comment it still does it :
res.on("end", () => {
try {
console.log("Req ended message is", body);
var passport = JSON.parse(body);
//TODO What if you get an array ?
if (passport._id) delete passport._id;
callback(passport);
} catch (e) {
w.info(
"Cannot parse the response from : " +
process.env.mongo_api_host +
" | error : " +
e
);
}
return;
});

}
}
please help me to solve this problem
Thanks in advance

Try using return statement for all the res.status() calls. So, even though once the response status gets set to something, it is again getting res.status() somewhere after it.
