Previous Info

There was already a ticket with a similar error:
https://issues.ibexa.co/browse/EZEE-3000
The solution was: install version 2.5.9 and remove the fields from block.
We did it, but now there is another error:
Pages cannot be published.

Description

An attribute of a block (here called testField) is never used anymore.
Therefore we removed this attribute (testField) from a module in blocks.yml and from the .twig-file.
The result is:

• all pages including such a module cannot be published anymore.

Reproduce Error

• 1.) Use an already existing block "test_module"
  --> find an instance with filled testField
• 2.) blocks.yml: Remove testfield
• 3.) Try to publish page
  --> page cannot be published
  --> Error-Message:
  Notice: Undefined index: testField
