Hi, and thanks for responding! fetch preflight fails and then throws a CORS error when actual client side fetch happens

@.wilbsy I assume you are using nextjs 13.4?

Turns out the endpoint was missing an AllowedHeaders: []string{"*"} which was the issue. But yes, we're running 13.4. Anyhow, thanks for your willingness to help!
