How to set Labels (advanced) with an array?

[Khira Niemeier]

We are currently trying to set up our Automation that is adding the Labels of the Parent, when creating a subtask.
So far we managed to add the labels, if it is only 1. So the problem appears, when there is more than one label to be set.

Our automation uses the following JSON:

{

"update": {
"labels": [{
"add": "{{issue.parent.labels}}"

}]

}

}

So I guess our question is: Is there a way to tell the automation that we need to use all of the labels in the array?

We already found out that  {{issue.parent.labels.size}}  will throwout the number of labels - but we didn't manage to create any solution with this info.

Hi @Khira Niemeier 

Rather than using an Advanced Branch to add the labels, I recommend using a list iterator over the parent values and add them with one single edit using a dynamic JSON expression for labels.  This will be faster, less likely to fail if there is a single rule error, and not cause any rule timing problems (due to the branch running in parallel and asynchronously).

For example:

• smart values condition: only proceed if the parent has labels
  • first value: {{issue.parent.labels}}
  • condition: does not equal
  • second value: leave this as empty
• action: edit issue with JSON to add the labels

{
  "update": {
    "labels": [
      {{#issue.parent.labels}}
        {
          "add": "{{.}}"
        }{{^last}},{{/}}
      {{/}}
    ]
  }
}

Kind regards,
Bill

Thanks @Bill Sheboy :) 
This solved the problem that we just encountered :D

Okay found the solution. :D 

We create an advanced branch and insert the array {{issue.parent.labels}} so it creates a smart value {{ParentLabel}} for every Label in the array. (as far as I understand)

And then we use the same Advanced Editing with a small change to {{ParentLabel}} instead of {{issue.parent.labels}}:

{

"update": {
"labels": [{
"add": "{{ParentLabel}}"

}]

}

}

 I hope it might help people who run into the same issue. ;)

We encoundered the next problem:
The Automation is too fast and does all the For steps at once (which leads to only one of the labels being set). 
The more Labels there are the less times it works.
Works with 2 Labels (sometimes):

Doesn't work with 3 or more:


If someone has an idea how to fix it let me know. :D 

Re-fetch issue Data doesn't help as it seems.
