TYPO3 Core

Error: "Uncaught (in promise) TypeError: Cannot convert undefined or null to object"

This happens when I want to search in a NEW (!) element for a searchable field (e.g. "Record Storage Page" in the content element "list").

This does not happen in an already stored element. In the 11 version it still worked.

But it becomes really problematic when this field should be a mandatory field (minitems = 1).

Now I have to describe a workaround to the customer.

I would be happy if someone could take care of this.
