In the Node.js environment, the `Http2Sessions` component fails to implement proper error handling for `ClientHttp2Session` during the initialization or reuse of HTTP/2 sessions. When a request is configured with `httpVersion: 2` and the `ClientHttp2Session` emits an error, the error bypasses standard Promise rejection handling. This uncaught exception can lead to the termination of the Node.js process, resulting in a denial of service.
