I'm getting 500 error message "Invalid argument supplied for foreach()" while trying to delete an image of "multiple image" field.

It says the error on Controllers/VoyagerBaseController.php on line 757.

...
       foreach ($rows as $row) {
            if ($row->type == 'multiple_images') {
                $images_to_remove = json_decode($data->getOriginal($row->field), true) ?? [];
            } else {
                $images_to_remove = [$data->getOriginal($row->field)];
            }

            foreach ($images_to_remove as $image) {
                // Remove only $single_image if we are removing from bread edit
...

I've checked that the $images_to_remove variable contains array data, but the error shows like the $images_to_remove is not an array.

Maybe it's bug of php7.3
