[bug\_fix] go: github.com/foo/[email protected]: reading at revision v1.2.3: unknown revision v1.2.3

Push the git tag to the remote repository using git push origin v1.2.3 \(or git push --tags\). If the tag was just pushed, wait a few minutes for the Go module proxy cache to update, or set GOPROXY=direct for the download.

Journey Context:
A developer creates a new version of their library, commits it, and tags it locally as v1.2.3. They push the commit to GitHub and then try to use go get github.com/foo/[email protected] in another project. The command fails with unknown revision. The developer verifies the code is on GitHub, leading them to suspect a Go toolchain bug. They check the git history and realize that while the commit was pushed, the tag was not. The Go module system relies on VCS tags to resolve semantic versions; without the tag on the remote, the proxy and VCS cannot find the version. Pushing the tag resolves the VCS lookup. Alternatively, if the tag was just pushed, the default Go module proxy \(proxy.golang.org\) may have cached a 404 for the version. In this case, waiting for the cache to expire or bypassing the proxy with GOPROXY=direct is required.
