"Access to fetch at 'https://fhir.epic.com/interconnect-fhir-oauth/api/FHIR/R4/Patient/xyzzz' from origin 'https://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'.
