Can media library validation catch more exceptions in the validation?

[davidyell]

I am interested to understand if there is a way to have the media library catch more exceptions as validation failures.

We have an occasional bug where we get League\Flysystem\UnableToRetrieveMetadata which comes from the src/Livewire/LivewireUploaderComponent.php class and it's getUploadError() method. This is when media-library tries to validate against a file which does not exist.

The stacktrace seems to indicate that the exception originates from the getUploadError() method.

    protected function getUploadError(): ?string
    {
        $uploadError = null;

        $field = $this->multiple ? 'upload.*' : 'upload';

        try {
            $this->validate([
                $field => $this->rules,
            ], ["{$field}.mimes" => __('media-library::validation.type')]);
        } catch (ValidationException $validationException) {
            $uploadError = Arr::flatten($validationException->errors())[0];

            if ($this->add) {
                $this->dispatch("{$this->name}:showListErrorMessage", $uploadError);
            }
        }

        return $uploadError;
    }

As you can see, it happily catches any ValidationException but does not handle any exceptions thrown from the Flysystem package, such as the UnableToRetrieveMetadata exception.

Is there a neat way to have any exceptions thrown by Flysystem be caught here and instead this method can throw a ValidationException?
