I am using keycloak for authenticating my spring boot API app.
the keycloak configuration is as below:
keycloak:
realm: totallr
resource: totall_api
ssl-required: external
bearer-only: true
auth-server-url: <my-server-with-port-commented-out>/auth
This works fine as such. But when I change some configurations through JVM args it fails with the following stack trace. The config I change is CORS origin from localhost to original domain and server port number.
ERROR org.apache.catalina.core.ContainerBase.[Tomcat].[localhost].[/totall/api].[dispatcherServlet] -
Servlet.service() for servlet [dispatcherServlet] in context with path [/totall/api] threw
