How to Fix Timeout 30000ms Exceeded in Headless Mode

Encountering timeout-30000ms-exceeded in headless-mode is a common hurdle for engineering teams. This guide provides a surgical approach to fixing the issue and ensuring your monitoring is resilient.

Error Impact Analysis

Quick Fix Steps

1. Verify Network Connectivity: Ensure headless-mode has access to the target URL.
2. Increase Navigation Timeout: Add page.setDefaultNavigationTimeout(60000).
3. Check Resource Limits: Increase memory/CPU if running in Docker or CI.

Playwright Debugging Script

import { test, expect } from '@playwright/test';

test('debug timeout-30000ms-exceeded in headless-mode', async ({ page }) => {
  // Set explicit timeouts for debugging
  page.setDefaultTimeout(45000);
  
  try {
    await page.goto('https://your-app.com', { waitUntil: 'networkidle' });
    // Add logic to trigger the error
  } catch (error) {
    console.error('Captured Error in headless-mode:', error.message);
    throw error;
  }
});

Solving the Maintenance Tax with supaguard

Instead of manually debugging timeout-30000ms-exceeded every time your CI environment changes, supaguard automates the recovery.

AI-Native RCA

Our Sanctum AI analyzes the execution trace and provides a human-readable explanation of why timeout-30000ms-exceeded occurred in headless-mode.

Automatic Region Verification

If a check fails in one region, supaguard automatically retries from another to confirm if the issue is global or specific to the headless-mode network.
