I’m getting that error when I run bench migrate command, how can I know what field is the problem?

Have you recently changed the default title for any doctype, say you set a field as the title of a document via Customize Form ? It seems there is an issue with some missing field.

I don’t remember to be honest :confused:
I’m trying debug by git commits now…

4

Huh! That’s not a app problem, now I need to find out what they changed in the system.
Now I got your point @root13F

5

Okay but still you can find those changes probably in Version filtering on Data field.
