I've correctly set up my Skill and my Lambda, hooked the two up and went to test it but I just get tonnes of errors in the console related to CORS headers (image below). My friend can run the same skill and setup as myself and his simulator works fine. I have tried in incognito with no extensions, I have tried on Firefox, Safari and have tried multiple networks (including a 4G hotspot). Consistently broken.
Whats the fix?
