SmartApp public key

[jwerfel]

I have created a self hosted NodeJS SmartApp. I’ve configured the SmartApp and the webhook and it is talking to my app. The app is verified but I don’t know where I can find the public key. Whenever I try to use my smart app on my phone I get an error. I debugged through and in authorizer.js it is failing on httpSignature.verifySignature (Forbidden - failed verifySignature). I assume that is because I don’t have the public key but I can’t figure out where I should get that from. When I view my smart app in the developer workspace I don’t see it anywhere. What am I missing?

Thank you,
Julian

I deployed my same code in glitch and it appears to work - I’m guessing the problem is with me using nginx.

Looks like someone else ran into this issue:

NGINX proxy for SmartApp Webhook Fails to Authorize

So I have a node.js app that is running the Smartthings node SDK and is hosted locally. Then I have an AWS EC2 NGINX server, nested in a Docker container on port 1234. The NGINX server has an SSL set up using Lets Encrypt. The local node.js app is connecting to the AWS NGINX server using an ssh tunnel. The NGINX config looks like this. Where the webhook url for the SmartApp would be https://example.com/tunnel/ server { listen 80; server_name example.com; location / { return 301 https://$host$request_uri; } location /.well-known/acme-challenge/ { root /var/www/certbot; } } server { listen 443 ssl; server_name example.com; ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; ssl_certificate_key /etc/letsencr…

Is there any reason why it would not authenticate through nginx?
