when running taps/targets/mappers, a quick fix is to add simpleeval==1.0.4 to your plugin's pip_url.
This was caused by a breaking change made in simpleeval==1.0.5 a few hours ago addressing a CVE: https://github.com/danthedeckie/simpleeval/releases/tag/1.0.5
We are working on fixes to the SDK and meltano-map-transformer now:
