BUILDKITE_PLUGIN_DOCKER_IMAGE: unbound variable

[CHR15-]

Hi!

/var/lib/buildkite-agent/plugins/github-com-buildkite-plugins-docker-buildkite-plugin-v3-5-0/hooks/command: line 339: BUILDKITE_PLUGIN_DOCKER_IMAGE: unbound variable

This has started occurring on our agents and nothing has changed from our end! Any ideas what this could be?

I just ran into this exact same thing, but haven't figured out why yet. 🤔

Oh, I was just using the wrong name for "image":
