The "required_by_role" plugin does not exist

I can reproduce this by setting up a field to use the 'Required by role' plugin, uninstalling the Required by role module and saving a node with that field.

I'm not sure what the best way to go would be though. I think the safest may be to fallback to the default behaviour (always required) when the chosen plugin is missing, but log a message to remind the site administrator to reconfigure the field.

I'm going to move this issue to the Required API module since this is something that needs to be fixed over there.

I added the fallback and error log in the MR. What still needs to be done:

• Show in the field edit form when a non-existing plugin is selected and allow to set back to default or another plugin
• See what happens when you completely uninstall the Required API module when fields are configured

Done!

See what happens when you completely uninstall the Required API module when fields are configured

The config related to Required API is removed from all fields and those fields are set to be always required. This seems like acceptable behaviour to me.
