Problems with current implementation of Moralis Cloud Code

Moralis General
#1

I’m having trouble reading token balance, incrementing it, and storing it back as a string.

Whenever I try out some function, the IDE (here VS Code) tells me that function is not available.

Currently, this is the code I use:

class PlayerReward extends Moralis.Object {
    constructor() {
        super("PlayerReward");
    }

    incrementRewards() {
        const rewardToAdd = Moralis.Cloud.units({
            method: "toWei", value: REWARD_PER_SIGNAL
        });
        const accumulatedReward = Moralis.Cloud.units({
            method: "toWei", value: this.get(KEY_ACCUMULATED_REWARD)
        });
        const newAccumulatedReward = Moralis.Cloud.units({
            method: "fromWei", value: accumulatedReward.plus(rewardToAdd).toString()
        });
        this.set(KEY_ACCUMULATED_REWARD, newAccumulatedReward);
    }
}
Moralis.Object.registerSubclass("PlayerReward", PlayerReward);

Obviously, it throws errors, such as this one:

2022-01-14T14:43:34.993Z - Error: Moralis units - Missing property `value`
    at Object.units (/moralis-server/lib/cloud-code/units.js:27:11)

  Input: {"signal":true}
  Error: {"message":"Moralis units - Missing property `value`","code":141}

Most Cloud functions are not recognised in Typescript:

So it’s impossible to solve the problem without the IDE acting as a crutch.

Any assistance will be truly appreciated!

I don’t know what is the problem there, you could try to use bignumer directly with a syntax like: new Moralis.Cloud.BigNumber("100000000")

#6

I wanted to say that you may be able to do what you want directly with big number without using units.

#7

I’ve tried all of those things before. The issue with trying directly with BigNumber is that I may get floating point errors if I factor in the decimals to get a Wei value.

#8

actually you will get floating point problems now if you use current implementation of Moralis.Cloud.units

Incredibly weirdly I’m getting an error for something which was working just yesterday when I run the query from the API Console:

2022-01-16T06:12:40.534Z - TypeError: Cannot read properties of undefined (reading 'getUsername')
    at Moralis.Cloud.define.fields (eval at customUserPlugin (/moralis-server/cloud/main.js:140:21), <anonymous>:1:1777)
    at processTicksAndRejections (node:internal/process/task_queues:96:5)
2022-01-16T06:12:40.529Z - Failed running cloud function sendActivitySignal for user undefined with:
  Input: {"signal":"true"}
  Error: {"message":"Cannot read properties of undefined (reading 'getUsername')","code":141}

This refers to me defining

    const player: Moralis.User = request.user;

and later attempting to log the username with player.getUsername().
This was working absolutely fine yesterday without the 0.0.329 update.

maybe you were not authenticated this time

#12

No, the user ID I’m testing for is definitely logged in/authenticated.

Problem has been solved!
