Local Docker image not found

I’m using Gitlab CI to pre-build my container and then run my tasks within that container. I have had this working in the past, but today, my build server was replaced (automated rebuild) and am having an issue that I can’t seem to track down. I’ve included everything I could imagine being relevant. Any suggestions would be appreciated!

The error message:

Running with gitlab-ci-multi-runner 1.8.1 (a2efdd4)

docker images snippet on gitlab runner as well as from both debug tasks in gitlab ci config

This appears to be a regression. I downgraded to 1.7.1 via sudo apt-get install gitlab-ci-multi-runner=1.7.1 and my builds began working again.

Created https://gitlab.com/gitlab-org/gitlab-ci-multi-runner/issues/1931 to track this.
