customObjectId does not work with beforeSave triggers

[buitanloc]

Issue Description

• customObjectId does not work with beforeSave triggers.

Steps to reproduce

• Turn on flag allowCustomObjectId on ParseServer
• Try to create a GameScore object with customObjectId objectId1 (from Android or iOS)
• Back to ParseServer, add beforeSave trigger for GameScore with empty body / function.
• Try to create the second GameScore object with customObjectId objectId2 (from Android or iOS)

Expected Results

• Received 2: GameScore objects with customObjectId: objectId1, objectId2.

Actual Outcome

• The first object has objectId is objectId1 while the second object has random id like this sMTH8Sq6jl

Environment Setup

• Server

  • parse-server version: 4.2.0
  • Operating System: N/A
  • Hardware: N/A
  • Localhost or remote server? (AWS, Heroku, Azure, Digital Ocean, etc): The problem happens on both localhost and Heroku

• Database

  • MongoDB version: 4.2.7
  • Storage engine: N/A
  • Hardware: N/A
  • Localhost or remote server? (AWS, mLab, ObjectRocket, Digital Ocean, etc): The problem happens on both localhost and mLab

I think inside PServer, It uses JS-SDK and in it, it is not yet implemented. parse-community/Parse-SDK-JS#1097

Any update on this? I am having same issue. I was saving custom object ids from express app, and it was working fine. And as soon as I add beforeSave trigger, it started discarding the provided custom ids, and stored objects with newly generated ids by parse.

So i found the reason and a solution.
getResponseObject calls _getSaveJSON this in turn removes the objectId.

A simple solution would be to add this to the resolver of getResponseObject . This fixes the issue - as it adds the id back if it is missing from modified object!

if (triggerType === Types.beforeSave && config.allowCustomObjectId && parseObjectJson.objectId) {
        object.object.objectId = parseObjectJson.objectId
}

another option would the to just remove _getSaveJSON if allowCustomObjectId is set. This should be fine as this is not called if a before save trigger ist not set, so removing it will probably not have any side effects. Checking ensures that it would change stuff in cases where the current codebase is already broken.

 if (request.triggerName === Types.beforeSave && !config.allowCustomObjectId) {
    response['object'] = request.object._getSaveJSON();
  }

It would be better if you could create a PR for this to further discuss this. @felix-ht

allowCustomObjectId has been added to the JS SDK and merged with the server.

#7222

I'll try to do a PR to fix this issue.

We countered the same issue and glad to know the bug fix has been merged. Any plans to release this fix in the soon future?

The first step would be to open a PR and demonstrate the issue with a failing test. From there, we can look for a fix.
