Troubleshooting

Common issues and fixes when integrating the SDK and verifying data in the dashboard.

No data appearing

Common causes

  • SDK tag not present / not loading
  • Wrong integration code
  • CORS or API URL misconfigured
  • No traffic yet

Quick checks

  1. Open browser DevTools → Network and Console
  2. Verify the script is loaded from /sdks/sublyzer.js
  3. Verify your data-integration-code is correct
  4. Verify your API is reachable (and CORS allows your frontend)
CORS (NestJS example)
app.enableCors({
  origin: ['http://localhost:3000', 'https://yourdomain.com'],
  credentials: true,
});
TestingAI runs failing
  • Ensure the target URL is reachable from the public internet
  • Check logs/stream endpoints in the dashboard
  • Try a smaller run (fewer agents/pages/clicks)
