JHipster gateway doesn't redirect to appropriate micro-services Not found, infinite loop with keycloak and JhipsterControlCenter not listing anything

[k888888888888888888]

Gateway unable to do request to microservices

1. When try to go to entities all I see is Not found when try to list and when try to create, is like is not pointing to the microservice at all.

2. When I try to locate my services at Instances in Jhipster control center I can't see anything, but I can see logs, configuration: http://localhost:7419/applications/instances this is empty.

3. Most of the times I got infinite loop using Keycloak when auth to my gateway :

Jwt: Signed JWT rejected: Another algorithm expected, or no matching key(s) found 2024-10-28T10:53:41.482+01:00 ERROR 1729734 --- [ XNIO-1 task-2] c.p.config.SecurityJwtConfiguration : Unknown JWT error An error occurred while attempting to decode the Jwt: Signed JWT rejected: Another algorithm expected, or no matching key(s) found 2024-10-28T10:53:41.864+01:00 ERROR 1729734 --- [ XNIO-1 task-2] c.p.config.SecurityJwtConfiguration : Unknown JWT error An error occurred while attempting to decode the Jwt: Signed JWT rejected: Another algorithm expected, or no matching key(s) found 2024-10-28T10:53:42.210+01:00 ERROR 1729734 --- [ XNIO-1 task-2] c.p.config.SecurityJwtConfiguration : Unknown JWT error An error occurred while attempting to decode the Jwt: Signed JWT rejected: Another algorithm expected, or no matching key(s) found 2024-10-28T10:53:42.598+01:00 ERROR 1729734 --- [ XNIO-1 task-2] c.p.config.SecurityJwtConfiguration : Unknown JWT error An error occurred while attempting to decode the Jwt: Signed JWT rejected: Another algorithm expected, or no matching key(s) found

Motivation for or Use Case

The generated application should be stable and working.

Reproduce the error

• jhipster jdl microservice.jdl
• cd microservice1
• docker compose -f src/main/docker/jhipster-control-center.yml up
• docker compose -f src/main/docker/jhipster-registry.yml up
• ./mvnw
• cd gateway
• docker compose -f src/main/docker/jhipster-control-center.yml up
• docker compose -f src/main/docker/keycloak.yml up
• ./mvnw
• ./npmw start
• go to localhost:9000 try to perform something at entities and enjoy the NOT FOUND. And eventually you will experiment the infinite auth loop.
• go to http://localhost:7419/applications/instances and you will not see anything.

Because currently the project is not stable, just generate something that do not works.
