Express-oauth2-jwt-bearer JWT.io issue

Help
,
1

I followed the tutorial at Auth0 Node (Express) API SDK Quickstarts: Authorization and created the middleware

const checkJwt = auth({
  audience: process.env.AUDIENCE_ID,
  issuerBaseURL: process.env.ISSUER_BASE_URL,
});

However, I get the error: AssertionError [ERR_ASSERTION] when trying to deploy to fly.io: You must provide an ‘issuerBaseURL’, an ‘issuer’ and ‘jwksUri’ or an ‘issuer’ and ‘secret’

Logs below:

Hey there @pytest3 welcome to the community!

While I can’t speak to deploying to fly.io, configuring the sample to my own environment and running/testing locally seems to be working as expected. Are you able to test the sample locally and confirm?

FWIW, if you have the audience and issuer_base_url values defined in your .env the auth() function should retrieve those for you automatically.

Are you positive you have require('dotenv').config(); in your own code? The error to me looks like the issuer_base_url isn’t getting set correctly.
