Solve the following python programming problem given the following code:
@ mock.patch ('aiohttp.client.os') 
@ mock.patch ('aiohttp.client.ClientSession.get') 
def test_ws_connect_custom_response(self, m_req, m_os) : 
    class CustomResponse (websocket_client.ClientWebSocketResponse) : 
        def read(self, decode = False) : 
            return 'customized!' 
resp = mock.Mock () 
    resp.status = 101 
    resp.headers = { 
        hdrs.UPGRADE : hdrs.WEBSOCKET, 
        hdrs.CONNECTION : hdrs.UPGRADE, 
        hdrs.SEC_WEBSOCKET_ACCEPT : self.ws_key, 
} 
    m_os.urandom.return_value = self.key_data 
    m_req.return_value = asyncio.Future (loop = resp.loop) 
    m_req.return_value.set_result (resp) 
    res = self.loop.run_until_complete (aiohttp.ws_connect ('http://test.org', ws_response_class = CustomResponse, loop = self.loop)) 
    self.assertEqual (res.read (), 'customized!') 

    
    

    Fix the buggy line: m_req.return_value = asyncio.Future (loop = resp.loop)

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

m_req.return_value = asyncio.Future (loop = self.loop)
