[SalesForce] Too many queueable jobs added to the queue: 2

I am trying to update user records using batch and I am getting this error

Too many queueable jobs added to the queue: 2

I found out that the batch update is triggering triggers on the user and one such trigger is using enqueue method. The enqueued method is using a future method to update contact records and there are no enqueued jobs in any other trigger.

So my question as I am enqueuing only one class why I am getting this error when I am trying to update ures records?

This is the trigger

if(trigger.isAfter){
    if(trigger.isUpdate){
        System.enqueueJob(new GlobalPRM_UserTriggerHelper(Trigger.New, Trigger.oldMap));
    }
}

See: https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_triggers_order_of_execution.htm

Executes all after triggers

...

Executes workflow rules.

If there are workflow field updates, updates the record again.

If the record was updated with workflow field updates, fires before update triggers and after update triggers one more time (and only one more time), in addition to standard validations. Custom validation rules, duplicate rules, and escalation rules are not run again.

It means that the trigger, that calls System.enqueueJob, can be run twice in one transaction.

[SalesForce] Queueable Job limit hit when trigger is batched

When run in Batch, you can only enqueue 1 job per execution of the batch so if your batch is causing the Trigger to enqueue more than 1, it will fail as described. I'll try to find a link to the docs describing this.

If your trigger is firing, from a batch apex process, and you have 2 Triggers firing that both enqueue a job, you will get the error because both the triggers fire in the same execution context (even though they are separate triggers).

For example:

Batch Apex
    Insert record(s)
        Trigger 1 (enqueue job 1 - ok)
        Trigger 2 (enqueue job 2 - fail)

The only way to get around that would be to ensure that only one enqueue job gets called across all triggers that fire.

[SalesForce] System.LimitException: Too many queueable jobs added to the queue

As you are chaining the jobs you have limit of 1 on child jobs. When chaining jobs, you can add only one job from an executing job with System.enqueueJob, which means that only one child job can exist for each parent queueable job. Starting multiple child jobs from the same queueable job isn’t supported.
