How to delete files using laravel

I am using DigitalOcean Spaces as a configured disk in Laravel and was having a problem with deletion of file using the following codes:

Source: https://laravel.com/docs/5.5/filesystem#deleting-files

Storage::disk('spaces')->delete('foldername/'.$fileName);

I have no problem uploading photos but I wanna have an option of replacing a file when a new one is uploaded. I tried this using my local disk and it worked, but when using do_spaces disk, nothing happens. I can even check that the file exists by using Storage::disk('spaces')->exists('foldername/'.$fileName); before trying to delete.

I am not sure if this is an issue in do spaces or is delete function like above is not supported here. Any idea what I’m doing wrong? Thanks
