[bug\_fix] go: [email protected]: invalid version: unknown revision ...

Ensure the tag exists in the upstream repository. If using a private repository, set the GOPRIVATE environment variable to bypass the public Go module proxy, which might not have access to the private repo.

Journey Context:
A developer pushes a new tag v1.2.3 to their private Git repository and updates go.mod to require this version. They run go build and get an unknown revision v1.2.3 error. They verify the tag exists in Git, so they assume the Go tool is broken or the proxy is slow. They might try go clean -modcache repeatedly or wait hours. The rabbit hole involves debugging Git authentication and network traces. The root cause is that by default, go get routes requests through the public Go module mirror \(proxy.golang.org\). The proxy doesn't have access to the private repository, so it returns 404/unknown revision. The fix is to set the GOPRIVATE environment variable to include the private repository's domain \(e.g., export GOPRIVATE=gitlab.mycompany.com\), which tells the Go toolchain to fetch directly from the source instead of the public proxy.
