I have deployed Apache NiFi with 3 nodes in kubernetes cluster. The Nginx ingress works fine with one node but not with more than one node with keycloak integration with OIDC. The session affinity setting as ClientIP in nifi service or session affinity annotation setting as "cookie" in Nginx ingress definition doesn't solve this issue.
Error displayed on Nifi UI page after keycloak authenticaation is as below:
Unable to continue login sequence
The login request identifier was not found in the request. Unable to continue.
