"When subitem created" trigger not firing

Platform discussions

I just wondered if anyone had encountered issues with the “When subitem created” trigger for initiating workflows? I have an existing (very key) workflow driven off this trigger which has inexplicably stopped working (Run History shows it was working successfully until some point yesterday).

I’ve rebuilt the workflow, I’ve built a super-simple workflow with the same trigger - nothing. Run History shows no indication that any new subitem has been created, ie the workflow doesn’t trigger at all, not that it has failed at some point further through the flow. So is definitely the trigger.

Is there anything that can suddenly cause a trigger or workflow to stop working? I seem to recall there being a limit on workflows per account - if that is reached would it simply pick arbitrary workflows to block? As that’s the only thing I can think of - other flows continue to work as they should.

Any help, thoughts, suggestions most welcome!

Last time I went ‘over’, it just wouldn’t let me create new, didn’t turn off old… I’m assuming you have Pro? How many active workflows do you have?

Hey Andy, Mia here from monday’s support team :smiling_face:

Thanks for reaching out about this—that is a critical part of your workflow, and I definitely understand your frustration with it suddenly stopping. I believe I can pinpoint exactly what is happening here, as our team has identified a bug with this specific trigger.

We have an active bug where the “When subitem is created” trigger in the Workflow Builder does not run if the subitem is created manually (i.e., by clicking the “Add Subitem” button). This perfectly matches the behavior you described: the workflow is not triggering, and there is no activity in the Run History.

The good news is we have a reliable workaround for this specific bug while we work on a fix:

  • Workaround: Instead of creating the subitem manually, you can use a simple automation to create the subitem.

    For example, you could set up a recipe like:

    When Status changes to “Create Subitem”, create subitem.

If you use an automation to create the subitem, the “When subitem is created” workflow should successfully trigger and run your subsequent actions. I would be happy to take a closer look and ensure you can get this key workflow back online as quickly as possible. Please DM me directly so I can gather a few account details and review your current setup!

I am having the same issue which is affecting multiple workflows, when can we expect this to be remedied?

Thanks for clarifying - definitely good to know I’m not going crazy (as is the conclusion I typically reach when every conceivable step has been tested and logically should work!).

Unfortunately triggering from a status change is not particularly practical in this context. To echo Sam’s question below do we have an expectation on when this should be fixed as I’m very reluctant to re-engineer a critical process and brief it out to a heavily-pressured team in the final weeks of the year.

Hi everyone! :waving_hand:

I’m happy to confirm that the issue with the “When subitem is created” trigger in the Workflow Builder has been resolved as of this morning!

Your workflows should now be triggering correctly when a subitem is created. You should be able to revert to your original setup without needing the temporary automation workaround.

  • If you are still experiencing any issues with this trigger, please DM me directly so I can open a support ticket and take a closer look at your specific account!

Thanks again for your patience as we worked through this fix!
