I worked with @techwithanirudh offline to resolve this … @techwithanirudh wasn’t aware of the chatbot uninstall instructions.
The giveaway here (atm) was the 502 due to the container not starting properly due to the index remaining in the db without supporting code in the postgres library. The uninstall instructions remove the index from the db so you can safely build without building the index library.
@techwithanirudh’s site is now up and running.
