oidc-auth: No 'Access-Control-Allow-Origin' header CORS error

[mkstowe]

Using the oidc-auth middleware with Auth0, I get a CORS error stating that the Access-Control-Allow-Origin header is not set. I'm not sure if this middleware is supposed to handle this or not, but the header is present when I don't use it. I am using the cors middleware as well.

My basic app/middleware setup:

const app = new Hono();

app.use(
  cors({
    origin: ["*"],
  })
);

app.use("*", oidcAuthMiddleware())

The error when trying to access any endpoint:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://<domain>.us.auth0.com/authorize?client_id=.... (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 302.

In Auth0, I do have the allowed callback urls and allowed web origins set as my app's url (currently just localhost:4200). I'm not sure if my issue lies in the setup of oidc-auth, cors, or both. Any help would be greatly appreciated!
