CORS problem while using submitTalk function

[redfish462]

What is the issue?

Hello, I followed the documentation on Install Story.

Everything is doing well, apart when I try to submit a talk, I have this error :

Access to fetch at 'https://us-central1-hey.cloudfunctions.net/submitTalk' from origin 'https://hey.web.app' 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. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

What is the expected behavior?
