Description

Today Github Actions based continuos delivery started to fail in build-and-push action with the error:

buildx failed with: ERROR: invalid key-value pair "": empty key

Nothing was changed in the system.

Expected behaviour

build-and-push does not break if nothing is changed.

Actual behaviour

build-and-push suddently stopped working with a new error message we (or no one else, for the matter) does not seem to encounter before.

Additional info

After clearing Github Actions caches the issue seemed to fix itself. Not sure if the issue was related to Github Actions caching, or a random fluke.

Any case I am leaving this issue report here, so if anyone encounters the error message again they have some information in hand.

Closing as the issue was appeareing randomly and it fixed itself.

My nemesis is back.

It was related to passing environment variables (commit message) from Github Actions to buildx which then passed them to --build-arg where it crashed.
