How to set "Original Estimate" for created custom issue type in Jira Cloud Automation?

[Wim Matthijs]

I made an automation which does the following:

1. Upon a release created, create an Epic for QA for this release
2. Fill that epic with QA-tasks

We have a custom issuetype for QA-tasks, and trying to set the Original Estimate in the automation leads to the following error:

Unknown fields set during create, they may be unavailable for the project/type. Check your custom field configuration. Fields ignored -

Time tracking (timetracking)

However, when i run the exact same automation with a regular task, all works well.

I really have the feeling that the time-tracking module is not integrated in the same way as the other JIRA fields for i have been having more problems getting automations to run properly.
See here: Can't monitor original estimate in Jira Automation... (atlassian.com)

If this is the case, is there maybe some documentation or roadmap available specifically about timetracking fields in JIRA?

much appreciated, thanks,

Wim
