Exit Code 1 after pushing latest tag

[CodeVachon]

Hello, last evening I found that this task in a job has started throwing an unknown error.

This occurs when the addLatest: true variable is set. When the value is not set, the task runs cleanly.

the latest image is built and deployed to the registry as expected, but reference tags are not.

Expected

expected to find 1 image with 2 tags in the registry.

• ghcr.io/***/anzen-api:latest
• ghcr.io/***/anzen-api:1.3.3 <-- tag name

Actual

only the latest tag is received on the registry

• ghcr.io/***/anzen-api:latest

---

my best guess would be that Actions has changed how git tag references resulting in ${{ github.ref }} being undefined, and that docker is throwing an error trying to set an empty tag as a result.

Update that This evening this issue appears to have resolved itself. likely an update that Github themselves made.

It would would still be nice to have a more verbose error message when something does wrong however.
