Hi, I’m having some problems when trying to assign a zeebe user task using zeebeClient.

I run Camunda 8.7 self-managed using docker-compose locally, in multi-tenancy mode.
I use the spring-boot SDK 8.7.

I create an instance of my workflow and then look up the user task using CamundaTaskListClient and then try to assign it to the demo user with the command

zeebeClient.newUserTaskAssignCommand

But I obtain the error NOT FOUND
I report some piece of logs:

If I try to assign and complete the user task from TaskList UI, all operations end successfully.

Thanks a lot for any suggestions,

Hi @crocie - I suspect that you need to enable the alpha endpoints. Not all of the new REST endpoints are out of alpha yet, but the alpha is quite stable and I recommend developing against it rather than waiting.
