Error: Received network error or non-101 status code.

Hi everyone! 😊

I hope you're doing well! I need some help with an issue I'm facing when connecting to Amazon Neptune using WebSockets.

Everything works perfectly when I use Node.js version 20.18, but when I upgrade to version 22 or higher, I start getting this error:

Error: Received network error or non-101 status code. at failWebsocketConnection (node:internal/deps/undici/undici:11629:18) at Object.processResponse (node:internal/deps/undici/undici:11842:13) at node:internal/deps/undici/undici:10623:23 at node:internal/process/task_queues:151:7 at AsyncResource.runInAsyncScope (node:async_hooks:211:14) at AsyncResource.runMicrotask (node:internal/process/task_queues:148:8) at processTicksAndRejections (node:internal/process/task_queues:105:5)

Do you have a minimal repro? The error is straightforward -- the websocket server is returning a response other than 101.

@IrocNinoNiel I also have the same issue. Were you able to get past it?

We started seeing this when using the ws package if the service returns a redirect.
