Worker is dropping Cookies

What is the issue or error you’re encountering

Worker is dropping certain cookies from the request

What steps have you taken to resolve the issue?

I am using vercel to host my react application. The cookies are properly set in the browser. I did the following to try debug

  1. Localhost → local worker (Wrangler dev): All cookies are being received , no issues.
  2. Vercel → Worker on Cloud: Cookies are being dropped.
  3. To ensure its not Vercel issue, I did Localhost → worker on cloud: Cookies are being dropped

I added page rule: Cache Level - Bypass for all routes in the worker’s custom domain but the issue still persists.
