Troubleshooting

Before submitting a bug report please read the Troubleshooting doc.

Behaviour

Warning: The `save-state` command is deprecated and will be disabled soon. Please upgrade to using Environment Files. For more information see: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

As per https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

Action authors who are using the toolkit should update the @actions/core package to v1.10.0 or greater to get the updated saveState and setOutput functions.

I can see the latest v3 release (v3.1.1) uses @actions/core@^1.9.0 https://github.com/docker/build-push-action/blob/v3.1.1/package.json#L31, and master has already been updated to @actions/core@^1.10.0 via https://github.com/docker/build-push-action/pull/695

Steps to reproduce this issue

1. use docker/build-push-action@v3 to build an image

Should be good with latest release

Frustratingly the actions UI doesn’t specify which one causes it
