Version: Rasa Enterprise 0.33.2

When trying to create a story in the Talk to your bot tab, the bot doesn’t respond. (see attached image) it hangs and there aren’t any visible errors in any component (Values.debugMode = true)

It seems that the tracker is not able to get either the domain or the policy ensemble for some reason, which leads to the message being processed by NLU, but no events being predicted by dialogue management:

@kronos-cm are you able to successfully interact with the tracker store over other channels?

4

This is resolved by downgrading to 2.0.2, versions 2.0.3-2.0.6 have issues with Rasa X’s model polling. There will be a patch in version 2.0.7 soon as well

5

No, it is the same for all channels

6

Version 2.0.7 has been released with the fix :rocket: it will be coming soon to 2.1.x as well.
