Solve the following python programming problem given the following code:
def _execute(self, desc, decoder, query, * args) : 
    'Runs a single query for a result set.

        Args:
            decoder - The function which can resolve the cursor results to
                something meaningful.
            query - The query string to execute
            *args - Query args.
        Returns:
            The result of decoder(results)
        ' 
    def interaction(txn) : 
        txn.execute (query, args) 
        if decoder : 
            return decoder (txn) 
else : 
            return txn.fetchall () 
return self.runInteraction (desc, decoder) 

    
    

    Fix the buggy line: return self.runInteraction (desc, decoder)
