Trying to Query Transactions

Moralis General
#1

I’m trying to get a transaction through moralis, I expected an object but got something strange, why does the response from the query is an object with “className”? I’m using moralis/node and not react so I didn’t expect that, also the properties on the object are not accessible, for example calling “transaction.from_address” is undefined and have only 4 keys, but when using JSON.stringify it shows the whole object as expected…

Why is that? and what is the right way to parse this?

This is the object I get:|

ParseObject {
  id: 'qdZ8jFbDD2kIBCjajh02KUzK',
  _localId: undefined,
  _objCount: 0,
  className: 'EthTransactions'
}

But then when I do JSON.stringify it has more fields…

somehow you can print that object contents with JSON.stringify

you can try ['from_address'] or .get syntax

calling transaction.from_address is undefined… I get the raw Parse object, I’m guessing you parse it it POJO for some queries. but for others you don’t.

For now the only way to get the underlying POJO/JSON is to convert the object to json which calls “toJSON” and that gives me the actual POJO, but that option is weird.

So I already know you guys work with parse, and this is the object I get:
https://parseplatform.org/Parse-SDK-JS/api/v1.11.1/Parse.Object.html

But wouldn’t it be nicer to convert it to a normal object?
Also based on the type definition it should return a proper object based on the generic type, which it doesn’t.

yes, we are using parse server, I would expect it to work somehow to get those attributes without the need to do that json conversion

can you paste some code that replicates it?

You should be able to just run this script with node, providing valid credentials.

import Moralis from "moralis/node";

const main = async () => {
  await Moralis.start({
    serverUrl: process.env.MORALIS_SERVER_URL,
    appId: process.env.MORALIS_APP_ID
  });

  const [myTransaction] = await new Moralis.Query("EthTransactions").find();

  if (!myTransaction) {
    throw new Error("you have no transactions");
  }

  // this is the issue I have
  if (myTransaction.from_address === undefined) {
    throw new Error(
      "Transaction is a parse object, when it should be a plain old javascript object (POJO)"
    );
  }

  console.log("yay, you solved it!");
};

main().catch(console.error);
