Webhook 400 BadRequest

I'm working off of this article.

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?

I found the issue with the first "quick start" article. I just needed to set the PORT to 5000 instead of 30001714074155255.png

Should I be seeing something on the Webhook-server.js terminal? When I send a SMS I don't see anything.

Thanks for pointing out. My bad when I tested the sample code the port 5000 was running and I forgot to change it to 3000 for most of the languages. I will fixed and release the update soon.

No Problem, I have one more question. I'm getting a Webhook is not reachable error. do you think you could switch my A2P Application to sandbox mode so I can do some development testing?

I'm thinking the prod environment is restricting my progress. I would make a brand new Application, but all my new application go straight into Prod for some reason.

No need to switch to sandbox mode. Sandbox is also supported after the app was created and auto-graduated. The app works on both environments.

A2P SMS is not supported in sandbox account thought.

So I try to create a subscription, but it doesn't stay open. I get this initially

It looks like the connect is open, but then it doesn't look like it stays open.1714155603021.png

Is that supposed to happen? If not, what am I doing wrong?
