Steps for linking Apollo client to Apollo server

I'm currently working through the Apollo tutorial located at https://www.apollographql.com/docs/tutorial/client/. My server is successfully running on localhost:4000, while my client is running on localhost:3000. Even though the client compiled without any issues, I'm encountering a 400 error in the browser that seems to be pointing to an Apollo error:

Uncaught (in promise) Error: Network error: Response not successful: Received status code 400 at new ApolloError (bundle.esm.js:76)
.

The tutorial makes use of TypeScript for the client, which was not previously installed on my system. I have since globally installed it, but apart from this change recommended by the tutorial, I have not altered anything else in the client. Unsure if this could be contributing to the issue.

For further information, the tutorial's repository can be found at https://github.com/apollographql/fullstack-tutorial.

Answer №1

Resolved: I discovered that the issue causing the 400 error was a mistakenly deleted field in a schema type. Additionally, there was a compilation error resulting from an error in a named import in another file. I successfully fixed this by changing it to a default import instead.
