Route with optional param is not working

this doesn't make any sense. are you really saying this is your url?
http://localhost/PROJECT/admin/product/image
how could that be a delete request when you are not specifying an id (number) to delete?

The delete request also takes a URL to delete temp images that don't have ID yet.
BTW the solution was

PHP Code:

$route["admin/product/image/?(:num)?"]["delete"] = "product/deleteImage/$1"; 


to make parameter optional.
even though the functions is defined as

PHP Code:

public function deleteImage($imageId=0) {
        $url = $this->sanitize->removeTags()->sanitize($this->commonlib->request("url"));
        if(!empty($url)){
            @unlink($this->config->item("temp_upload_dir").$url);
            $this->commonlib->sendResponse(200, "Product Image Removed");
        }
        else{
            
        }
    }
