• Windows

Runner type:

Hello @arodland 👋,
Thank you for reporting this issue. We will investigate it and get back to you as soon as we have some feedback.

Hi @arodland, The issue you're facing during cache restoration is due to the telemetry update in Go 1.23.0. This update includes files (config.json, go.mod, LICENSE, doc.go) that already exist in the golang.org/x/telemetry directory, causing conflicts. When restoring the cache, these existing files prevent the tar command from completing successfully, resulting in "File exists" errors.

We have observed that the error related to extracting telemetry files is not present in Go version 1.23.1. Attached a screenshot for your reference This suggests that the issue might have been resolved in the newer release.
We recommend updating your workflow to use Go version 1.23.1 as follows:

- name: Set up Go
  uses: actions/setup-go@v5
  with:
    go-version: 1.23.1

If you continue to experience issues, please let us know.

I can confirm that the issue doesn't occur with go 1.23.1, and I suppose that's good enough. Closing.
