Can't get "clientAuthentication is not a function" to go away

Hi,
Sorry if it's been asked a million times, I can't figure this out. Trying to integrate SSO with OIDC (using Authentik for testing) and running into the issue in the title.

server-1  | [ERROR] OIDC callback error: TypeError: clientAuthentication is not a function
server-1  |     at authenticatedRequest (file:///app/node_modules/oauth4webapi/build/index.js:1050:11)

Here are the files in question, the issue is with fetchUserInfo supposedly, can't see where though, is it somewhere internal?

Any help appreciated, cheers.

From a cursory look you just need to completely remove the options object that isn't a valid value for the clientAuthentication argument of client.discovery()

Doh. Thank you.
