Description: page.setContent() hangs indefinitely and hits a timeout when using CloakBrowser, whereas the exact same operation succeeds instantly using standard Playwright Chromium.
CloakBrowser version: [email protected]
Wrapper: JavaScript ([email protected])
Environment: Windows 10 22H2
Launch options: Default launch() configuration.
Tested with a different IP or proxy? No
Works outside Docker / on host machine? Not using Docker
Steps to reproduce:
import { chromium } from 'playwright-core';
import { launch } from 'cloakbrowser';
async function testStandard() {
console.log('\n--- 1. Testing Standard Playwright Chromium ---');
const browser = await chromium.launch();
const page = await browser.newPage();
console.log('Calling page.setContent...');
await page.setContent('<h1>Hello from Standard Chromium</h1>', { timeout: 5000 });
console.log('✓ Succeeded on Standard Chromium!');
await browser.close();
}
async function testCloak() {
console.log('\n--- 2. Testing CloakBrowser Chromium ---');
const browser = await launch();
const page = await browser.newPage();
try {
console.log('Calling page.setContent...');
await page.setContent('<h1>Hello from CloakBrowser</h1>', { timeout: 5000 });
console.log('✓ Succeeded on CloakBrowser!');
} catch (e) {
console.error('✗ Failed on CloakBrowser:', e.message);
} finally {
await browser.close();
}
}
async function run() {
await testStandard();
await testCloak();
}
run();Error output / screenshots:

Additional notes: Standard Playwright Chromium handles this successfully in less than a second. The issue is isolated to CloakBrowser
