POST request Help

I’m trying to build out a function that will accept a payload of IDs, query the DB and return related documents.

At the moment I have these values hardcoded in my function, but the client calling this API is getting an empty object.

My function is:

 exports = async function (payload, response) {

   const collection = context.services.get("mongodb-atlas")
                      .db("mydb")
                      .collection("my collection");

const foundWantedCards = await collection.find(
 { card_id: { $in: [ "61ddf66c68ebbba1a4084e65", "61ddf5b768ebbba1a4fd2c33" ] }, forTrade:"Yes" }
);

return foundWantedCards
}

When I run this function within the editor I get a result

> result: 
[
  {
    "_id": {
      "$oid": "61e995ff2738954edae011ec"
    },
    "card_id": "61ddf5b768ebbba1a4fd2c33",
...

which is correct, but the value of FoundWantedCards is empty. How should I return the result in the reponse?

Also, how should I access the payload that is sent in the POST request? I’ve tried via EJSON.parse(payload.body.text()) but again that is empty.

Any help much appreciated!

OK, I am successfully getting a response back now, but I still can’t figure out how to access the payload in the POST request. payload is truncated in my logs so I can’t see all the values, but payload.body doesn’t show anything. I’ve tried looking in context but can’t find anything either.

In my logs I do see an object

    },
    {}
  ]
}

an I assume that the body property here is the encoded payload, but how do I access this in my function?
