Firebase Functions in Custom Region CORS Error

I have been using Firebase again recently to build a simple app for Esther who is a Piano teacher. I’ve not used it for several years and things have definitely come a long way. The ability to use serverless functions is really exciting.

I am based in England and so I am using the europe-west2 region to deploy my functions but when I tried to call the function from my browser code I got a CORS error.
