[keycloak-user] Help Communicate between apps with a scheduled task

Hi all, I need to executed some code inside a scheduled task using Spring Boot. Inside this task I have to contact another web-app in order to retrieve some information. Both of them use Keycloak. The problem is that when that task starts, I have the error: Cannot set authorization header because there is no authenticated principal Why? How can I communicate between app using keycloak auth without do a login? I mean, how can I run a task autocamatically? Becuase if I call manually that method it works Thank you!
