Hello auth0 community,

I’m trying to follow the steps at https://auth0.com/blog/auth0-s-express-openid-connect-sdk to begin the process of working with auth0, nodejs, and express. I followed the ‘local dev’ guide to set up caddy and proxy to SSL.

My express app is throwing the following every time I try to access https://localhost/login (which should show an auth0 lock screen):

(node:48241) UnhandledPromiseRejectionWarning: AggregateError:

(node:48241) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 2)

It was working at some point prior. I triple-checked that my auth0 app details/credentials are accurate. Anyone encounter something similar to this or have any tips?
