I know this is a closed issue, but I found this after searching for a solution for a similar issue. I believe I have worked out the cause of the problem. If you have an upload field named file_upload, the javascript component in backpack will submit this as a single file type input field on create. However, when you edit the file, this field is not present unless you try to upload a new file. As a result, the Laravel validation doesn’t see a file_upload key in the request input, and throws the validation error.

The problem then comes if someone clicks the remove button when editing, as the javascript of the form element will create an empty file_upload field, which will trigger the removal of the file through the standard crud process, as this is viewed as an effort to delete the uploaded object.

So the question is then, how to have validation that checks that either the input doesn’t have a file_upload attribute (in which case we know that the Crud won’t delete the current file), or if it does that it is not empty.

Awesomely, it turns out Laravel has you covered. The validation rule just needs to be:

'file_upload' => 'sometimes|required'
