⚠️ We've moved!

Hi there!

To reduce project dependency on 3rd party paid services the StackStorm TSC has decided to move the Q/A from this forum to Github Discussions. This will make user experience better integrated with the native Github flow, as well as the questions closer to the community where they can provide answers.

Cannot start mistral workflow in ST2 3.1

We upgraded to st2 3.1 and we cannot execute mistral workflows. The actions work fine. The logs show me this error:

Please check Unable to run Mistral workflows and it has some steps to fix psql and some useful links related to debug.

What was the old st2 version before upgrading to latest v3.1?

Did you follow Upgrade Procedure instructions? Upgrades — StackStorm 3.1.0 documentation
and Upgrade Notes: Upgrade Notes — StackStorm 3.1.0 documentation

We went from 2.9 to 3.1.

A few more important facts. We are running in K8s, and we have deployed successfully to a DEV and INT environment, using same exact procedure (Helm Charts, etc). Both previous env’s worked without issue. When we deployed to our PROD env, that’s where things went south. Last night i followed the procedure here: Upgrades — StackStorm 3.1.0 documentation
bringing down all ST2 services and running this:
/opt/stackstorm/mistral/bin/mistral-db-manage --config-file /etc/mistral/mistral.conf upgrade head
/opt/stackstorm/mistral/bin/mistral-db-manage --config-file /etc/mistral/mistral.conf populate | grep -v -e openstack -e keystone -e ironicclient

Then st2ctl reload, to no avail. I will try to get some better error messages this morning.
