Error message after migration to J4: Joomla\CMS\Filesystem\Folder

Hello

After I have migrated to J4 I have an issue.

On checkout page I get a warning message:

Warnung
Joomla\CMS\Filesystem\Folder::files: Der Pfad ist kein Verzeichnis! Pfad: Joomla\CMS\Filesystem\Folder::files

Update:
For some reason the warning message has gone away...

But if I do order, I get an error:
Sorry, there was a problem we could not recover from.
The server returned a "500 - Whoops, looks like something went wrong."

Can you please have a look at it?
Thanks a lot.

Regards
Patrick

Hi

Since the warning message has gone away magically, this issue is solved.


Thanks.
