问题
I am working on a microservice architecture developed in Spring boot with an API gateway service using Spring Cloud Gateway. I am using Keycloak as an identity provider. Everything is working fine normally, but I am getting intermediate authorization_request_not_found exception on user login and a whitelable error page occurs. If we try again, it works.
Below is the exception I received on Keycloak server:
[org.keycloak.broker.oidc.AbstractOAuth2IdentityProvider] (default task-264) Failed to make identity provider oauth callback: org.keycloak.broker.provider.IdentityBrokerException: No access_token from server.

As far as I have seen, there is no pattern or a scenario when this exception occurs. It just occurs randomly. I have visited several blogs and other stack overflow issues but I can't figure it out what's wrong in my configs.
Is there any way I can find out what is wrong ?
Any help is much appreciated. Thanks in advance!
