How to Handle Errors in Camunda 7 vs Camunda 8 – Retries, Incidents & BPMN Errors Explained (2026)
Introduction
Error handling is one of the most critical aspects of workflow automation.
In Camunda, handling failures correctly ensures:
- System reliability
- Process consistency
- Better user experience
But Camunda 7 and Camunda 8 handle errors very differently.
In this guide, we’ll cover:
- Retries
- Incidents
- BPMN Errors
- Real-world handling strategies
🏗️ Error Handling Overview
Key Difference:
- Camunda 7 → Transaction-based error handling
- Camunda 8 → Event-driven error handling
👉 This changes everything from retries to debugging.
🔁 Retries Handling
🔹 Camunda 7 (Retries)
- Managed by Job Executor
- Configurable retries (default: 3)
- Uses async continuations
Example:
camunda:failedJobRetryTimeCycle="R3/PT5M"
👉 Retries happen automatically within the engine
🔹 Camunda 8 (Retries)
- Controlled by external workers
- Worker decides retry logic
- Uses backoff strategies
Example (Java Worker):
client.newFailCommand(job.getKey())
.retries(job.getRetries() - 1)
.send();
👉 More control, but more responsibility
⚠️ Incident Handling
🔹 Camunda 7 Incidents
- Incident created when retries = 0
- Visible in Cockpit
- Manual retry possible
👉 Centralized debugging
🔹 Camunda 8 Incidents
- Managed via Camunda Operate
- Happens when retries reach zero
- Can retry from UI
👉 Designed for distributed systems
🔄 BPMN Errors (Business Errors)
🔹 Camunda 7
- Use BpmnError in Java
throw new BpmnError("ERROR_CODE");
- Handled using:
- Boundary Events
- Error Events
👉 Clear separation of technical vs business errors
🔹 Camunda 8
- Thrown from workers
client.newThrowErrorCommand(job.getKey())
.errorCode("ERROR_CODE")
.send();
👉 Fully aligned with event-driven architecture
📊 Quick Comparison
| Feature | Camunda 7 | Camunda 8 |
|---|---|---|
| Retries | Engine-managed | Worker-managed |
| Incidents | Cockpit | Operate |
| BPMN Errors | Java delegates | Worker-based |
| Execution | Sync + Async | Fully Async |
| Debugging | Centralized | Distributed |
🧠 Best Practices
For Camunda 7:
- Use async before/after for retries
- Separate technical & business errors
- Monitor via Cockpit
For Camunda 8:
- Implement retry logic in workers
- Use exponential backoff
- Handle idempotency
- Monitor via Operate
⚠️ Common Mistakes
- ❌ Treating business errors as technical failures
- ❌ Not configuring retries
- ❌ Ignoring idempotency in Camunda 8
- ❌ Overusing synchronous patterns
🧠 Final Thoughts
👉 Camunda 7 = Easier error handling (engine-driven)
👉 Camunda 8 = More flexible but developer-controlled
✔ Simple apps → Camunda 7
✔ Scalable systems → Camunda 8
