I’m doing requests with Graphql and Apollo Client to a backend project made with Phoenix. I had a problem because the request failed and the Chrome console shows me the error “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.”
I used CORSICA and CORSPlug to allow access but it didn’t work. Please, anyone has an example or solved that error?
Thanks!
