Hi,
I'm working off of this article. https://developers.ringcentral.com/guide/notifications/webhooks/quick-start
and I get a /502 Bad Gateway error on my ngrok terminal and a 400 Bad Request on my Webhook-notification.js terminal.
My code seems to be failing at this point in the subscribe_for_notification function.
I also tried this tutorial and I get see a 400 Bad Request error but also a OAU-251 error instead. I error out during the login here. I've tried both basic auth and JWT

Also I don't know if this is related, but when I register a application, it goes straight into Production instead of Sandbox. Is that normally how that should happen?
Is there something that I'm missing?
