Sorry, something went wrong (see error above). Make sure to start Rasa X with valid data and valid domain and config files. Please, also check any warnings that popped up. If you need help fixing the issue visit our forum: http://forum.rasa.com/.

I am not sure if my issue related with asyncio. I often encountered a TimeoutError after idling the shell mode for a while. Would it be the main cause? How can I resolve the issue?

nik202 · September 16, 2021, 6:07am

@arthurchan Hello! Can you type rasa --version in your virtual environment and share the screenshot please.

arthurchan · September 16, 2021, 6:11am

nik202 · September 16, 2021, 6:22am

@arthurchan

I’d recommend to create a fresh conda environment with python 3.7 or 3.8 and follow the step

`pip install rasa==2.8.1`
 #I guess it will install both rasa and rasa-sdk else please install rasa-sdk==2.8.1

check version rasa --version its install or not

then

pip install rasa-x==0.39.3 --extra-index-url https://pypi.rasa.com/simple

check rasa version rasa --version its install or not

You will see some error : ImportError: cannot import name ‘RowProxy’ from ‘sqlalchemy.engine’ Install

pip install SQLAlchemy==1.3.22 should fix it

If sanic related error: pip install sanic-jwt==1.6.0

delete .db if is showing alembic issue.

@arthurchan If you have any error, please let me know.

Good luck! I hope this will solve your issue.

@nik202 Thanks for the prompt reply. It worked after following the steps. However, I have caught another error message:

Do you have any idea?

nik202 · September 16, 2021, 7:10am

@arthurchan can you please delete the cookies and cache from the web browser and try run please?

@arthurchan This is just a warning, can you confirm you are able to take with bot and you getting back the response?

@arthurchan Can you even share the above error screenshot and rasa version to.

arthurchan · September 16, 2021, 7:36am

@nik202 I had deleted the cookies and cache from the web browser and run again.

@nik202 I tried to talk to my bot and it seemed to respond to me as expected.

@nik202 Below are the screenshots from my command line

@nik202 Below shows my rasa version:

nik202 · September 16, 2021, 7:41am

@arthurchan This is can be the issue of the network as it showing TCP connector. I guess your bot is fine and you can work. It should not affect your bot/user conversation. If there is any further solution I will share with you

@arthurchan I would also like to request to please close this thread with the solution for others.

Good Luck!
