Error in website

I encountered a CORS (Cross-Origin Resource Sharing) error. The error message in the browser console states: "Access to XMLHttpRequest at 'https://firestore.googleapis.com/google.firestore.v1.Firestore/Listen/channel?VER=8&database=projects%2Fbuilder-3b0a2%2Fdatabases%2F(default)&RID=57643&CVER=22&X-HTTP-Session-Id=gsessionid&zx=ayq8y3nnhm1b&t=1' from origin '[Your Domain]' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource
