            $uploadedFile = $request->file('upload');
            $filename     = $this->getUploadedFilename($field, $uploadedFile);

It seems like $uploadedFile defined by $request->file('upload') on line 580 can also be of type array or null; however, Yajra\DataTables\DataTablesEditor::getUploadedFilename() does only seem to accept object<Illuminate\Http\UploadedFile>, maybe add an additional type check?

            $id           = $storage->putFileAs($this->uploadDir, $uploadedFile, $filename);

            if (method_exists($this, 'uploaded')) {
                $id = $this->uploaded($id);

The method uploaded() does not exist on Yajra\DataTables\DataTablesEditor. Did you maybe mean upload()?

            }

            return response()->json([

The method json does only exist in Illuminate\Contracts\Routing\ResponseFactory, but not in Illuminate\Http\Response.
