After the running, I checked in the web UI if the status changed, and it didn't —the running finishing without any errors or replies.

I failed to update the "STARTED AT" and the "COMPLETED AT" attributes in the "INFO" tab.

I'm not sure this can actually be overridden...

I couldn't change the task status from draft to complete

Task.completed(ignore_errors=True)

what's the error/reply ?

Task.completed(ignore_errors=True)

I tried to use it, but the status still unchanged.

Hi TimelyPenguin76 ,
the code example is:
task = Task.create(project_name="projectX", task_name='Y') task.completed(ignore_errors=False)

Hi SpotlessFish46 ,

can you send a code example? I want to try reproduce it on my side

Task.completed(ignore_errors=False)
What are you getting?

I got the following Error:
2020-10-27 19:26:57,222 - trains.Task - ERROR - Action failed <500/0: tasks.completed/v2.2 (unsupported operand type(s) for -: 'NoneType' and 'datetime.datetime')> (force=False, task=9bbd60866e5646c8aacad418ae7fc86f, status_reason=completed)

Hi SpotlessFish46

In order to mark task as completed, it should start first, can you try:

task = Task.create(project_name="projectX", task_name='YYY') task.mark_started() task.completed()?

Great! now it's working. The status changed to completed.
Thanks TimelyPenguin76 !
