Default message: upstream registry returned 404 for this coordinate; verify the package name and version
HTTP status:404(client)
Problem. The upstream registry returned 404 for this coordinate. Cause. The package name, namespace, or version does not exist in the configured upstream — commonly a typo or a version that has been yanked. Fix. Verify the coordinate against the ecosystem’s registry UI. If the package was yanked, pin to a known-good prior version. HTTP 404.
