Error Message

`League\Flysystem\Filesystem::has(): Argument #1 ($location) must be of type string, null given`

Solution

The error message itself was not immediately clear, but the issue was caused by the exists method in the following code:

$isFile = Storage::disk('s3')->exists($url); // Error occurs if $url is null

This started happening after upgrading a project originally developed in Laravel 5 or 6 to Laravel 10.

Previously, when exists() received null, it would return false without any issues. However, it seems that now it only accepts a string, and null is no longer allowed (though I am not sure of the exact change).

You can fix this by wrapping it with an if statement like this:

$isFile = false;
if($url){
    $isFile = Storage::disk('s3')->exists($url);
}

I hope this helps someone.
