Asyncio - Task exception was never retried

I keep facing this error over and over again, even though I have reverted my directory to the old commit. The action server was connected, but whenever rasa calls the form it crash

2019-10-09 15:17:44 ERROR asyncio - Task exception was never retrieved future: <Task finished coro=<configure_app..run_cmdline_io() done, defined at c:\users\quynt\anaconda3\envs\rasa_env\lib\site-packages\rasa\core\> exception=TimeoutError()> Traceback (most recent call last): File “c:\users\quynt\anaconda3\envs\rasa_env\lib\site-packages\rasa\core\”, line 127, in run_cmdline_io server_url=constants.DEFAULT_SERVER_FORMAT.format(“http”, port) File “c:\users\quynt\anaconda3\envs\rasa_env\lib\site-packages\rasa\core\channels\”, line 138, in record_messages async for response in bot_responses: File “c:\users\quynt\anaconda3\envs\rasa_env\lib\site-packages\”, line 366, in step return await ANextIter(self._it, start_fn, *args) File “c:\users\quynt\anaconda3\envs\rasa_env\lib\site-packages\”, line 205, in throw return self._invoke(self._it.throw, type, value, traceback) File “c:\users\quynt\anaconda3\envs\rasa_env\lib\site-packages\”, line 209, in _invoke result = fn(*args) File “c:\users\quynt\anaconda3\envs\rasa_env\lib\site-packages\rasa\core\channels\”, line 103, in send_message_receive_stream async for line in resp.content: File “c:\users\quynt\anaconda3\envs\rasa_env\lib\site-packages\aiohttp\”, line 39, in anext rv = await self.read_func() File “c:\users\quynt\anaconda3\envs\rasa_env\lib\site-packages\aiohttp\”, line 328, in readline await self._wait(‘readline’) File “c:\users\quynt\anaconda3\envs\rasa_env\lib\site-packages\aiohttp\”, line 296, in _wait await waiter File “c:\users\quynt\anaconda3\envs\rasa_env\lib\site-packages\aiohttp\”, line 586, in exit raise asyncio.TimeoutError from None concurrent.futures._base.TimeoutError Transport closed @ (‘’, 50853) and exception experienced during error handling

The only way is downgrade the version of Rasa to 1.1.1, but then I cannot use Retrieval Action and the ResponseSelector NLU component

The problem is fixed when I used rasa==1.3.3 and rasa-sdk = 1.3.3

@TQuy How did you continue with this old version after solving this problem? Are there future errors will come up after downgrading? :frowning:

can you describe your problem with the code if you can?
