CORS Policy issue when intergrating ackee with Next.js

[milindsoorya]

I tried to install ackee using this article https://kickstart.app/blog/web-analytics-with-ackee-on-vercel. I used the vercel route and after deploying it to production getting CORS error, please help.
This is the error
Access to XMLHttpRequest at 'https://ackee-analytics-orpin.vercel.app/api' from origin 'https://www.picturetalkies.in' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

It sounds like the ACKEE_ALLOW_ORIGIN environment variable is either not set or incorrectly configured.

Here're a few links that could help:
