After up-gradation from 12.0.8 to 12.1.0 my custom field deleted from Items doctype. is this happens for any up-gradation?
The upgrade should not delete any custom fields.
I have previously upgraded as well and all my custom fields are still there.
Just maybe it’s a cache issue ? alternatively try to rebuild the JS and CSS with
bench update --build
thank you. I have already added the field again as of now.
