This appears to be related to timeout configuration changes and the shift to REST as default protocol in Camunda 8.8+, which can cause DEADLINE_EXCEEDED errors during debugging with breakpoints. I found the following relevant resources:
- DEADLINE_EXCEEDED - Failed to activate jobs for worker
- C8run timeout between gateway and broker
- Gateway configuration documentation
- Camunda 8.9 migration guide
- 8.8 Release announcements - API changes
Does this help? If not, can anyone from the community jump in?
