How to catch Issuer.discover failure?

[austinjreid]

Describe the problem

How do I catch an error when the OP is not available?

I receive this error in the console and the application crashes:

AggregateError: Issuer.discover() failed.
    RequestError: connect ECONNREFUSED 127.0.0.1:8024
    RequestError: connect ECONNREFUSED 127.0.0.1:8024
    at Function.discover (E:\code\app1\node_modules\openid-client\lib\issuer.js:265:17)
    at runMicrotasks (<anonymous>)
    at processTicksAndRejections (node:internal/process/task_queues:96:5)
    at pReflect (E:\code\app1\node_modules\p-reflect\index.js:5:17)
    at async Promise.all (index 0)
    at E:\code\app1\node_modules\p-memoize\index.js:33:22
    at get (E:\code\app1\node_modules\express-openid-connect\lib\client.js:43:18)
    at pReflect (E:\code\app1\node_modules\p-reflect\index.js:5:17)
    at async Promise.all (index 0)
    at get (E:\code\app1\node_modules\p-memoize\index.js:33:22)

Thanks for any help!

What was the expected behavior?

I would expect to be able to catch the error in the application and handle it accordingly.

Reproduction

Use example app, take OP offline, attempt authentication

Environment

express-openid-connect: 2.7.2
node: 16.15.1

Thanks for raising this @austinjreid

Opened #371 to fix, which should surface the error in your express error handler https://expressjs.com/en/guide/error-handling.html
