Solve the following python programming problem given the following code:
@ defer.inlineCallbacks 
def remove_tag_from_room(self, user_id, room_id, tag) : 
    'Remove a tag from a room for a user.
        Returns:
            A deferred that completes once the tag has been removed
        ' 
    def remove_tag_txn(txn, next_id) : 
        sql = 'DELETE FROM room_tags  WHERE user_id = ? AND room_id = ? AND tag = ?' 
        txn.execute (sql, (user_id, room_id, tag)) 
        self._update_revision_txn (txn, user_id, room_id, next_id) 
with self._account_data_id_gen.get_next () as next_id : 
        (yield self.runInteraction ('remove_tag', user_id, next_id)) 
self.get_tags_for_user.invalidate ((user_id,)) 
    result = self._account_data_id_gen.get_max_token () 
    defer.returnValue (result) 

    
    

    Fix the buggy line: (yield self.runInteraction ('remove_tag', user_id, next_id))

#Here is Python program to fix the buggy line: (yield self.

(yield self.runInteraction ('remove_tag', def remove_tag_txn(, next_id))
