ONE user getting login error for ood_core-0.29.0 not found

I have a single user whose attempts to login are failing with a stack of errors in /var/log/ondemand-nginx//error.log that begin with

App 3721559 output: /usr/share/gems/gems/bundler-2.5.22/lib/bundler/definition.rb:599:in `materialize’: Could not find ood_core-0.29.0 in locally installed gems (Bundler::GemNotFound)

and continue with a traceback. The user has no ~/.bundle or ~/.gems I can find.

Anyone got clues?

Hey sorry for not replying here - I believe we solved this in slack. The issue was you had updated OnDemand to the next version that had ood_core-0.29.0 but did not bounce the PUNs to pick up an update.

This is just in case anyone comes to see this after so long.
