I have next error:
Access to fetch at 'https://api.constantcontact.com/v2/contacts?action_by=ACTION_BY_VISITOR&api_key=mw*****kt' from origin 'http://localhost:3000' 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.
