I followed a note from the actions/cache (link).

Seems to work fine in my project.

After: 35s

Feel free to remove ba9f365 and build on your own.

Wow, great find.

I wonder if we should update our typescript template repository to always do this. I struggle to see any downside.

Pushed as v5.1.1 and @v5 updated.

I had to revert this as v5.1.2. We found that the build failing does not fail the step anymore.

Notice here the build failed, but it proceeded to upload the artifacts. Since the failing step did not set the local-bin output, the path: / option to upload-artifact generated a confusing error message.
