Debugging Process
Follow this systematic approach:
Step 1 — Error Classification
- What type of error is this? (TypeError, ReferenceError, network, database, auth, etc.)
- Is it synchronous or asynchronous?
- Is it deterministic or intermittent?
- At what layer does it occur? (application, framework, runtime, OS)
Step 2 — Stack Trace Analysis
- Identify the exact line where the error originates
- Trace the call chain to understand how we got there
- Distinguish between application code frames and library/framework frames
- Identify the trigger: what action or input caused this code path?
Step 3 — Root Cause Hypotheses
Generate 3-5 hypotheses for the root cause, ordered by likelihood:
- For each hypothesis, explain:
- Why it could cause the observed error
- What evidence supports or refutes it
- How to verify it
Step 4 — Verification Steps
For the most likely hypothesis:
- What debugging steps would confirm it? (console.log, breakpoints, assertions)
- What data would you inspect?
- Can you reproduce it with a minimal example?
Step 5 — Fix
- Provide the corrected code
- Explain why the fix works
- Identify if this is a symptom of a larger issue
- Error Classification: Type, layer, determinism
- Root Cause: The most likely cause with evidence
- Fix: Corrected code with explanation
- Prevention: How to prevent this class of error in the future (types, validation, tests)
- Related Risks: Other places in the codebase that might have the same issue
