Solve the following python programming problem given the following code:
def _patched_get_conn(self, connection_pool_class, connection_class_getter) : 
    get_conn = connection_class_getter._get_conn 
    @ functools.wraps (get_conn) 
    def patched_get_conn(pool, timeout = None) : 
        connection = get_conn (pool, timeout) 
        connection_class = (pool.ConnectionCls if hasattr (pool, 'ConnectionCls') else connection_class_getter ()) 
        while (not isinstance (connection, connection_class)) : 
            connection = get_conn (pool, timeout) 
return connection 
return patched_get_conn 

    
    

    Fix the buggy line: get_conn = connection_class_getter._get_conn

#Here is Python code to fix the buggy line: get_conn = connection_class_getter.

get_conn = connection_pool_class._get_conn
