Failed to fetch registry info for ${pkg}, got status ${res.s

Error message

Failed to fetch registry info for ${pkg}, got status ${res.status}

What it means

Registry lookup failure in fetchPkgInfo while checking optional SWC dependency versions for lockfile correction: the HTTP fetch of `${registry}${pkg}` returned a non-ok status. The registry URL comes from getRegistry(), so misconfigured registries or unavailable packages produce this error.

Solutions

1. Check network/registry availability and retry the install so the lockfile can be patched.
