Accessing query values in HTTP POST Third Party Service

MongoDB Atlas App Services & Realm Atlas Triggers & Functions
1

Hi,

I’m confused by the way two HTTP services are behaving differently.

The first service is based on the tutorial at GitHub - mrlynn/stitching-sheets: Stitching Sheets: Using MongoDB Stitch to Create an API for Google Sheets and has a hook based on stitching-sheets/source.js at master · mrlynn/stitching-sheets · GitHub

exports = async function(payload) {
   console.log('here is payload query object ' + JSON.stringify(payload.query));
   const mongodb = context.services.get("mongodb-atlas");
   const eventsdb = mongodb.db(“my”db);
   const eventscoll = eventsdb.collection(“my collection");
//create values for the payload items sent to the endpoint
    const user = payload.query.user;
    const userName = payload.query.userName;
    const year = payload.query.year.substr(0, 4);
    const player = payload.query.player;
    const manufacturer = payload.query.manufacturer;
    const brand = payload.query.brand;
    const series = payload.query.series;
    const grader = payload.query.grader;
    const graded_id = Number(payload.query.graded_id);
    const career_stage = payload.query.career_stage;
    const team = payload.query.team;
    const card_number = Number(payload.query.card_number);
    const print_run = Number(payload.query.print_run);
    const number = Number(payload.query.number);
    const image_path = payload.query.image_path;
    const forTrade = payload.query.forTrade;
    const status = payload.query.status;
    const purchase_date = payload.query.purchase_date;
    const card_id = payload.query.card_id;
const result= await eventscoll.updateOne({ card_id: card_id },
{ $set: { 
  user:user,
  userName:userName,
  year: year,
  player:player,
  manufacturer:manufacturer,
  brand : brand,
  series : series,
  grader : grader,
  graded_id : graded_id,
  career_stage : career_stage,
  team : team,
  card_number : card_number,
  print_run : print_run,
  number : number,
  image_path : image_path,
  status : status,
  forTrade:forTrade,
  purchase_date : purchase_date
  } 
},
{ upsert: true }
);
  console.log('here is payload object ' + JSON.stringify(payload.query));

  if(result) {
     console.log('here is result ' + JSON.stringify(result));
     //return JSON.stringify(id,false,false);   
   }
   return { text: `Error saving` };
}

From Google App Script I POST to this via

var options = {
  method: "post",
  payload: formData, //a JSON representation of the cells in the Google Sheet
};
if (player) {
  var insertID = UrlFetchApp.fetch(
    "https://webhooks.mongodb-realm.com/api/client/v2.0/app/cards-fvyrn/service/AddCards/incoming_webhook/Aards",
    options
  );

This all works fine from Google Sheets. However I want to make POST request to the same endpoint via Axios or POSTMAN but I get an error
‘“error”: “{"message":"Cannot access member ‘substr’ of undefined"}”,
“error_code”: “FunctionExecutionError”,
‘

I’ve created another test POST endpoint with the code

exports = async function (payload, response) {
//console.log("payload.query "+ JSON.stringify(payload.query));
console.log("payload.body"+JSON.stringify(payload.body));

   const query = EJSON.parse(payload.body.text())
   console.log("payload.query "+ JSON.stringify(query));

    const results = await context.services
        .get("mongodb-atlas")
        .db(“my db)
        .collection("my collection")
        .insertOne( query )

    response.setBody(results ? JSON.stringify(results) : "{}");
}

I can send the same JSON object to this endpoint and it is submitted to the collection fine. I’m confused about why in this second function I am not able to access any properties of payload.query (e.g. payload.query.career_stage from the first example) but instead have to access the query values via
const query = EJSON.parse(payload.body.text()).

Also, can anyone suggest how I could amend this service to accept an array of objects, so that where the document IDs match the document is updated, and where there is no match a new document is created? Sorry if this last question should be a separate question :slight_smile:
