Debugging with Blurs AI

Blurs AI can help you understand and fix bugs by analyzing error messages, stack traces, and code patterns.

Error Analysis

Understanding Error Messages

Paste error messages to get explanations:

I'm getting this error: "Cannot read property 'name' of undefined"
What does it mean and how do I fix it?

Blurs AI will:

• Explain what the error means
• Identify likely causes
• Suggest fixes
• Provide code examples

Stack Trace Analysis

Analyze complex stack traces:

Here's my stack trace: [paste stack trace]
Help me understand what went wrong and where.

Code Debugging

Finding Bugs

Submit code for bug detection:

Review this code and identify potential bugs: [paste code]

Explaining Unexpected Behavior

When code behaves unexpectedly:

This function should return the sum of numbers, but it's returning 
undefined. What's wrong? [paste code]

Common Debugging Scenarios

Null/Undefined Errors

I'm getting "Cannot read property 'map' of undefined" on this line:
const items = data.items.map(...)
How do I fix it?

Async/Await Issues

My async function isn't working correctly: [paste code]
Help me debug the async/await logic.

State Management Issues

My React component state isn't updating correctly: [paste code]
What's wrong with my state management?

API Errors

My API request is failing with status 401. Help me debug: [paste code]

Debugging Workflow

Step 1: Describe the Problem

Explain:

• What you expected to happen
• What actually happened
• Any error messages
• Relevant code snippets

Step 2: Get Analysis

Blurs AI will:

• Analyze the problem
• Identify likely causes
• Suggest debugging steps
• Provide potential fixes

Step 3: Apply Fixes

Try the suggested fixes:

• Test each suggestion
• Verify the fix works
• Check for side effects

Step 4: Verify

Ensure the fix:

• Solves the original problem
• Doesn't break existing functionality
• Follows best practices

Best Practices

Provide Context

Include:

• Full error messages and stack traces
• Relevant code sections
• Expected vs actual behavior
• Steps to reproduce

Be Specific

Instead of "it doesn't work", describe:

• What you're trying to do
• What happens instead
• When it happens

Include Environment Info

Mention:

• Framework and version
• Browser or runtime
• Recent changes
• Related dependencies

Race Conditions

I'm experiencing a race condition. Help me fix it: [paste code]

Tips for Effective Debugging

1. Start with the error message - Most errors tell you what's wrong
2. Isolate the problem - Narrow down to the specific code causing issues
3. Check recent changes - Recent modifications are often the culprit
4. Use step-by-step debugging - Understand the execution flow
5. Test assumptions - Verify what you think is happening

Common Patterns

Pattern: Missing Null Checks

Problem: Accessing properties of undefined/null
Fix: Add null checks or optional chaining

Pattern: Missing Error Handling

Problem: Unhandled promise rejections
Fix: Add try/catch or .catch() handlers

Pattern: Incorrect Dependencies

Problem: useEffect running too often
Fix: Review dependency arrays
