What is the community experience with Websphere Liberty OIDC?

I’m working on a project to authenticate Websphere Liberty with OIDC and running into this issue:

[ERROR] CWWKS1520E: A request to [https://internal-curamserver-ts1-alb-902628124.us-west-2.elb.amazonaws.com/oidcclient/redirect/casemanagement01] is not valid. A required cookie with a name that begins with WASReqURLOidc is missing. The host name that is used to access the client might not match the name that is registered at the provider. A response code of 500 is returned.
