Camunda 8 Worker using spring-boot-starter gets errors from Camunda

Everytime any worker is online, it keeps throwing errors in the logs:

io.camunda.zeebe.client.job.poller : Failed to activate jobs for worker calculateBusinessDateWorker#calculateBusinessDateHandler and job type calculate-business-date

io.grpc.StatusRuntimeException: INTERNAL: Received unexpected EOS on non-empty DATA frame from server

Some batch processes (cancellation and deletion) in Operate run for weeks.

The worker itself runs, and completes correctly…
But the logs are full of the error above.
