Layout builder warning: Field failed to render with error of ""

Created on 16 March 2023, almost 2 years ago
Updated 11 October 2023, about 1 year ago

I'm using an editable field (list text) via layout manager and when a user triggers a field update, three things happen:
- the value is updated
- an uncaught AJAX HTTP error occurrs
- a watchdog entry is created by layout_builder: field failed to render with the error of ""

I've tried several config adjustments but to no avail. I just seem to not grasp why this is happening.

    I don't know the reason why it happens yet. But I've found a workaround by patching core for fields related to this module.

    If the exception handling is removed for fields related to this module it does the trick - no exceptions thrown. Though I don't know why the exception handling causes the problems though - or rather brings the problems to light?
