No error handling in FileUploadController.php and Dropzone.vue

[senecolas]

Issue

In a dropzone, some of my images could not be uploaded and no toast error message was displayed.
In console, the error message is only 'File not provided'. But after investigation, the error was simply due to the exceeds of the upload_max_filesize ini directive: so the message returned by the server is not correct.

Proposed solution

• Add a toast message on error inside Dropzone.vue
• Replace FileUploadController::upload from :

public function upload(Request $request): JsonResponse {
    // "hasFile" does not take into account files that have errors
    if ($request->hasFile('file')) {
        $path = $request->file('file')->store('', ['disk' => 'uploads']);

        return response()->json(['path' => $path], 200);
    }

    return response()->json(___('craftable-pro', 'File not provided'), 422);
}

to

public function upload(Request $request): JsonResponse {
      if ($request->files->has('file')) {
            $file = $request->files->get('file');
            if ($file->isValid()) {
                $path = $request->file('file')->store('', ['disk' => 'uploads']);
                return response()->json(['path' => $path], 200);
            } else {
                $errorMessage = $file->getErrorMessage();
                // TODO: add translation or log it ?
                return response()->json($errorMessage, 422); 
            }
     }
    return response()->json(___('craftable-pro', 'File not provided'), 422);
}
