Solve the following python programming problem given the following code:
def get_yaql_interpreter(self, node_id) : 
    context = self._yaql_context.create_child_context () 
    context ['$%new'] = self._transaction.get_new_data (cache) 
    context ['$%old'] = self._transaction.get_old_data (node_id) 
    cache = self._yaql_expressions_cache 
    def evaluate(expression) : 
        logger.debug ('evaluate yaql expression: %s', expression) 
        try : 
            parsed_exp = cache [expression] 
except KeyError : 
            parsed_exp = self._yaql_engine (expression) 
            cache [expression] = parsed_exp 
return parsed_exp.evaluate (data = context ['$%new'], context = context) 
return evaluate 

    
    

    Fix the buggy line: context ['$%new'] = self._transaction.get_new_data (cache)

#Here is Python program to fix the buggy line: context ['$%new'] = self.

context ['$%new'] = self._transaction.get_new_data (node_id)
