looking through my register.py I see nothing broken and it doesn't even seem to be evaluated

Is the custom plugin in the repo?

when I saw this issue I tried with

backend_packages.add = ["plugin1", "plugin2"]

as well as

backend_packages = ["plugin1", "plugin2"]

neither worked

@jolly-doctor-21349 Is

docker_python_image

a symbol your plugin registers? That is, are you using that name in BUILD files or in

pants.toml

?

In BUILD files
