TYPO3 Core

*Versions of relevant Components:

Typo3-Version: 12.4.3
PHP Version: 8.1
CMS-Form: 12.4.3

*Steps to Reproduce:

Step 1: Configuration of Sitepackage as storage option:

We have used forms and configured the site package as an additional option for saving as follows.

persistenceManager:
allowedExtensionPaths:
10: EXT:gartenlandooe/Resources/Private/Forms/
allowSaveToExtensionPaths: true
allowDeleteFromExtensionPaths: true

Step 2: Create new form and save it within the site package, then try to delete it.

Saving works as expected. However, on the deletion of a form saved within the sitepackage, an error is thrown. It says that the resource does not exist, although it does.
