You are not allowed to access files outside your storages

This exception is thrown in FAL whenever you are trying to access a file outside of your configured storages. The default storage is fileadmin (see https://docs.typo3.org/m/typo3/reference-coreapi/master/en-us/ApiOverview/Fal/Index.html).

In backend modules this exception will occur if files in legacy folders/storages are accessed, which is prohibited due to security reasons (see https://review.typo3.org/#/c/23608/).

Solution

Either try to access files in a valid storage instead (like fileadmin/_temp_/ instead of (uploads/not/working) or add the desired folder to a storage configuration.
