Keycloak : Failed to Obtain Policy Enforcer Error

Question

Problem:

I'm currently using Keycloak 15.0.1 with Spring Boot 2.7.15 within a Docker environment. Approximately six months ago, I successfully built the application, and it has been functioning as expected since then. I haven't made any changes to either the application or the Keycloak container. However, I now intend to add more functionality. When attempting to make various requests, including those to accessible endpoints, I encounter the same error consistently.

Description of the Problem:

Upon inspecting the Docker container logs for Keycloak, I noticed the following entry: docker container logs

The error I encounter when making any request is depicted below:

• application logs
• postman request
• postman response

What I Have Tried:

I attempted to make the request directly from Postman to Keycloak and succeeded: postman

Additionally, I verified that the YAML configuration matches that of Keycloak, and it indeed matches:

# spring config

  security:
    oauth2:
      resourceserver:
        jwt:
