AxiosError: Request failed with status code 500 (Slack Bot Integration)

I have my app deployed locally on ip/port. I am in Connections, and trying to get the ‘Connect to Slack’ running with Bot options. I add the correct bot token and get failures in console in browser of ‘AxiosError: Request failed with status code 500’. http://xx.232.1xx.242:8081/api/v1/app-connections?projectId=abc123&limit=10000 500 (Internal Server Error)

This fails to create the connection and thus integration with Slack. I had the integration working on 0.28.0 but now with 0.91.0 I cannot.

Also on the Connections page before I even load anything its showing:
Trouble loading connections

Nothing has been lost — your data is safe. Try again in a moment.

Try again

The page is: http://xx.232.1xx.242:8081/projects/EWm6Suzw2jrR0NDh8q8Xp/connections?limit=10

I’ll try an upgrade to 0.92 if this helps.
