Disk "webdav" cannot be accessed when using Spatie Media Library

[fhsdmhacc]

Hello,
I'm experiencing an issue with Spatie Media Library when attempting to store media to a WebDAV disk. I'm able to successfully store files using Laravel's built-in Storage::disk('webdav') function, but when using addMedia() from Spatie Media Library, I receive the following error:

Spatie\MediaLibrary\MediaCollections\Exceptions\DiskCannotBeAccessed: Disk named webdav cannot be accessed.

I've configured the webdav disk in config/filesystems.php with correct WebDAV credentials and base URI. When I try to run this code, I receive the error above.

$model->addMediaFromString('test')->usingFileName('test.txt')->toMediaCollection('test', 'webdav');

I would appreciate any help or guidance on how to resolve this issue.
Thank you!
