Download failed with status {}: {url}

Error message

Download failed with status {}: {url}

What it means

download_bytes got an HTTP response but its status was not success (404, 5xx, etc.) for the requested tool URL. The bundler surfaces the status code and URL so the failing download source can be identified.
