hello @VladimirAus I Tried to reproduce the error following the process you have mentioned, but i didn't get this error also the form is working fine to me, either we need more info about how to reproduce this error or there may be some issue with any other module in your peoject, causing this issue,

Closing it for now.

I was able to reproduce this. Once you install the module and visit the general setting page you get this warning as the default value for view mode is not set and the array key is missing from the config. Attached patch please review.

The setting is both in default config (config/install/diff.settings) and was set by an update hook.

The only way I could see to trigger this error is to not run an update hook after upgrading.

I will need steps to reproduce. Fixes also must be in an MR.

It is still reproducible after running updb.

I've followed the steps in the IS and after running database updates there is no error. If you're still getting the error simply save the form to set the config.
