Trying to import build summary (.dockerbuild or .dockerbuild.zip) in Docker Desktop v4.42.0 (for mac) created with build-push-action fails with message:

Failed to import build record: {"error":"unrecognized image
format", message": "Internal Server Error"}

Expected behaviour

Import works as described in https://docs.docker.com/build/ci/github-actions/build-summary/ and https://docs.docker.com/desktop/use-desktop/builds/#import-builds

Actual behaviour

Import fails

Additional info

Import also fails with a randomly picked build summary from build-push-action CI:

Thanks for reporting, we are taking a look

It seems to be imported correctly on my side:

Can you create a diag report: https://docs.docker.com/desktop/troubleshoot-and-support/troubleshoot/#diagnose?

It seems to be a UI issue in Docker desktop, which only appears when dragging the archive into the upload area:

Selecting the archive via "Browse file" or importing it via docker buildx history import works fine.

Thanks for the super quick reply! Closing here, as this clearly isn't a build-push-action issue.

Ah thanks, I will report that!
