Stitch service EJSON

MongoDB Atlas App Services & Realm

Hello friends!

I am working with an Incoming Webhook. When i do this:

exports = function(payload, response) {

var collection = context.services.get("mongodb-atlas").db("FEDEX").collection("empleado");
var retorno = collection.findOne();
return retorno;

};

Returns well but in EJSON format:

{
horaMarcaje: { ‘$date’: { ‘$numberLong’: ‘1576802718000’ } },
tipoMarcaje: { ‘$numberInt’: ‘0’ },
SN: ‘BWXT191960344’,
tipoLector: ‘huella’
}

I try to solve it this way:

exports = function(payload, response) {

var collection = context.services.get("mongodb-atlas").db("FEDEX").collection("empleado");
var retorno = collection.findOne();

response.setHeader("Content-Type", "application/json");
response.setBody(JSON.stringify(retorno));
response.setStatusCode(200);

};

But I get this: {}

How do I get the function to return a JSON instead of an EJSON?

Thanks!

I would use https://docs.mongodb.com/stitch/functions/utilities/ to convert the answer.

I could fix it!
Problem with promises. I was missing the await in:

var data = await collection.findOne();

This works perfect:

exports = async function(payload, response) {

try {
var collection = context.services.get(“mongodb-atlas”).db(“FEDEX”).collection(“empleado”);
var data = await collection.findOne();

    var dataJson = JSON.stringify(data);
           
    response.setHeader("Content-Type", "application/json");
    response.setBody(dataJson);
    response.setStatusCode(200);
  }

catch(error) {
console.error(error);
}
};

I don’t think you need to await the JSON.stringify function. Its sync.

What do you mean? Do you mean you want the date in some other format? Can you show what format you need back?

Thanks Asya!

The issue was that I didn’t know how to respond with JSON instead of EJSON.

But I could fix it

Thank you!

Thanks Ihsan!

I could solve it, the problem was that I was missing the “await” in the query:

var data = await collection.findOne ();

Thank you!
