I am working with Drupal Version 10.2.6 and PHP Version 8.1.28
I created a paragraph with:
1 number field (page number)
1 text filed (for the short note)
I added the paragraph to a simple content type for short notes about a book
If I try to create a note with the added paragraph the following message is shown:
Oops, something went wrong. Check your browser's developer console for more details.
the Protocoll shows php error:
