Debugging Misroutes
Why did it go left instead of right?
Debugging Misroutes
The most common bug in LangGraph is the Router going the wrong way.
- Symptom: User asked for "Tech Support" but got "Sales".
- Debug: Look at the Router Node output in the trace.
- Did the LLM output "SALES"? (Prompt issue).
- Did the LLM output "SUPPORT" but the code mapped it to
SalesNode? (Logic issue).
Tracing isolates the "AI Failure" from the "Code Failure".
