Memory exhausted error if settings.storage is empty

[beckerr-rzht]

I'm using Typo3 10.4.12 with fal_securedownload 3.0.0.

I have created a page that contains nothing more than a plugin of type "falsecuredownload_filetree".
There I then "forgot" to select a storage, so I left "settings.storage" empty.

Problem

When I call the page I see the following error:

Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 110592 bytes) .../ForViewHelper.php on line 133
