When I block the third party cookies, both your example (EyeTracker_webgazer210) and my own project fail to run with the same errors reported earlier. When I toggle Chrome Developer Tools (F12 on Windows/Cmd + Opt + I on Mac) on the calibration screen, I found the following error message. What’s going on here…?
Uncaught (in promise) TypeError: Cannot read properties of undefined (reading '0')
