Error sending a GraphQL mutation to the Tasklist API in a self-managed container

Hi Camunda,

I get an error when running mutations through the self-managed Tasklist API with Keycloak. The error message is “User is not authenticated” but I already received my access token and authenticated my request with Bearer token authorization. In fact, I can easily get tasks with the same authentication settings and the error only occurs on mutations.

I found a forum thread already mentioning issues on claimTask on a self-managed container: https://forum.camunda.io/t/tasklist-api-claimtask-user-doesnt-have-the-permission-to-assign-another-user-to-this-task/37938.

Is it possible that there are restrictions regarding mutations in the self-managed setting?
Thank you for your attention and we look forward to your reply.

I would also be interested in this topic on claiming and completing Tasks via the API in the self-managed version. Has anybody the same issue or maybe even a solution?
