I've got the same error when trying to push the a new version of the Einstein bot from a sandbox to production.
I believe it might be to do with the fact the our sandboxes are on the Summer 23' pre-release whilst our production org is on the SprintSpring 23'release and my. My guess is there has been some changes in the backend which aren't compatible with the different versions.
This is just a guess as I was able to push my bot through the pipeline with no issue as they're all on Summer 23' but have hit this snag with trying to push it to Production, meaning I'll have to manually make my changes.
Hope this helps!
