Looks like a regression to me, all scrapes impacted. This is an opprtunity to setup unit trsting and at least test that this conversion works fine. Once done, would be easier to extend.

Unit testing would not help, it's not a code issue. It's a Dockerfile issue. We changed base image and unfortunately that strong requirement was included in non-slim image but not declared so switching to slim had it missing. End-to-end test would have been able to catch it.

Reran that recipe and it succeeded with 1.2.1. All recipes changed to 1.2.1 but I didn't schedule anything else
