The Errors panel displays runtime errors from your deployed applications. Use it to identify issues in production, understand error patterns, and resolve problems quickly.

​
Error Details

Each error displays:
  • Error message — the exception text thrown by your app
  • Stack trace — the full call stack showing where the error originated
  • Environment context — environment variables, request details, and app state at the time of error
  • Occurrence count — how many times this error has occurred
Errors are automatically collected from your app’s container runtime and organized by error type and frequency.

​
Automatic Error Collection

Errors from your application are automatically collected and aggregated — no additional configuration needed. Major captures runtime errors from your app code and surfaces them in the Errors panel.

​
Ask AI to Fix

Click the Ask AI to fix button on any error to send the full error details to the AI chat in the editor. The AI uses the message, stack trace, and context to:
  • Identify the root cause
  • Suggest code changes to resolve the issue
  • Walk you through the fix step-by-step
This shortcut skips copying and pasting error details manually — the AI has everything it needs to start debugging immediately. The panel updates automatically as new errors occur in your deployed app. You can review error history to spot patterns and address systemic issues before they affect more users.
