Solve the following python programming problem given the following code:
def _clean_req(self, request, method, results) : 
    ' stop the request from returning objects and records any errors ' 
    cb = request.callback 
    @ wraps (cb) 
    def cb_wrapper(response) : 
        try : 
            output = cb (response) 
            output = list (iterate_spider_output (output)) 
except : 
            case = _create_testcase (method, 'callback') 
            results.addError (case, sys.exc_info ()) 
def eb_wrapper(failure) : 
        case = _create_testcase (method, 'errback') 
        exc_info = (failure.value, failure.type, failure.getTracebackObject ()) 
        results.addError (case, exc_info) 
request.callback = cb_wrapper 
    request.errback = self 

    
    

    Fix the buggy line: request.errback = self

#Here is Python code to fix the buggy line: request.
