Hi peops,
so here is the thing - I might just not understand something or something isn't working correctly.
This is what I'm working with:
- SharePoint Online List with two content types
- Power Automate Flow (when a new item was created or modified) that is supposed to fill out the title and the reminder date, trigger conditions: if the last editor was not USERX
- No workflow history
- Error if triggering something manually
Here are my steps:

Click on trigger and change the item:

Go back to my flow and then I get this error:

My content types titles are both optional, so I don't know why this is showing up. My workflow history is completely blank, too.
What I tried out:
- I deleted just my trigger and added it back, didn't work
- I deleted my Flow and created a new one with the same actions, didn't work
- I hid the title field in the settings of my content type, didn't work (changed it back to optional and tried again, but that was also not working)
Can someone please help me out with this?
Update: Just checked again, but it seems like my field is set up to be optional, but if I open up a form it's not optional?!
