I have two applications hosted on Netlify right now: one serves my frontend and one serves my backend. The frontend was made using create-react-app and my backend was created using a Netlify + express + graphql tutorial I found. When I ping the backend from the frontend locally, everything returns fine and I am able to run my queries. When I try this in production, I don’t see anything. My requests say 200, but no response body is returned. I figure it has something to do with my toml file.
Can you give us an example URL on the first site and what URL should be served for the second site being proxied to? With that information we should be able to suggest a redirect that meets those requirements.
Sorry to be slow to respond here. Is this still occurring for you? If so, can you please provide more information about what steps have you been taking to recreate this error?
