When trying to run Rasa X, got "revision not found" error

Hi guys! I’m really enjoying to project using rasa stack, thanks for the wonderfull work

I’ve used rasa x before many times, but today I am experiencing a strange error: when running “rasa x” on terminal, I get this error, which I did not found anywhere:

Traceback (most recent call last):

The above exception was the direct cause of the following exception:

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/.

Additionally, when running locally, everything works fine.

Any ideias?

Thanks in advance!

Hey @lgabs,

We typically recommend running deploying Rasa X to a server in order to collection conversations, you would need to leave it continually running, etc.

That being said if you want to fix this issue can you tell me what version you are running? It might be worth updating to the latest as well depending on what version you are on atm.

The alternative locally is running Rasa Open Source and using rasa shell to interact with your assistant then deploy Rasa X on a server setup for other users to communicate with it and be able to annotate and update your assistant from these conversations.

Thanks

I get this after changing the Rasa x version in the .env file:

It would be great to have some more information on this error.

By the way, I am running with docker compose.

Here the portion of my .env file related to rasa x:

RASA_X_VERSION=0.26.1
RASA_VERSION=1.8.0
RASA_X_DEMO_VERSION=0.26.0

It was all working fine until I switched the versions testing to get a working pair of RASA_X_VERSION and RASA_X_DEMO_VERSION

akelad · March 16, 2020, 12:42pm

@argideritzalpea what was the version of Rasa X you were using previously?

argideritzalpea · March 23, 2020, 2:59am

@akelad

RASA_X_VERSION=latest
RASA_VERSION=1.8.0
RASA_X_DEMO_VERSION=0.26.0

The above had been working for me until I updated Rasa X to 0.26.1 following the Rasa X update instructions. Now, switching back from 0.26.1 to latest won’t work also (updating, of course) - when I try to converse with models I train and curl to Rasa X, the chat “…” remains “typing” a response forever, and won’t refresh in the UI. When I restart the containers, however, I will see that the chat indeed proceed as expected and text is returned.

I also consistently receive this error when I attempt to discard changes in Git from the UI:
