Hi @guillaumecostanza

Sorry that you ran into this! It is indeed a bug in the migration which can happen when you have either in progress or failed intent insights reports at the time of the migration running.

I’ve just fixed the migration and released a new version (0.39.3). Can you please try upgrading to 0.39.3?

hey @chdorner I am unable to update to 0.39.3, I get the following error when I try to do that

for nginx manifest for rasa/nginx:0.39.3 not found: manifest unknown: manifest unknown

I have raised this separately too here
