Hi All ,
I’m facing the issue while authenticating TaskList client for selfManaged authentication
clientId and clientSecret I’m using of tasklist
The code used for creating client :
CamundaTaskListClient clientT = CamundaTaskListClient.builder()
.taskListUrl(“http://localhost:8082”)
.selfManagedAuthentication(“tasklist”, “tasklist-client-secret”,“http://localhost:18080/auth/realms/camunda-platform/protocol/openid-connect/token” )
.build();
logger.info(“Tasklist client created: {}”, clientT);
I’m getting the following error
java.lang.NullPointerException: null
