Error: Apollo Client requires config file

When I execute a query in VSCode, I get the following result -

Error: graphql operation failed t: GraphQL Config file is not available in the provided config directory: -PROJECT ROOT DIRECTORY- Please check the config directory.

Some research suggests there is meant to be a .graphqlconfig file. I can’t find any configuration files in the folder structure. Should there be one? Is this just a VSCode thing? The error object is returning a 400 code. The query is working ok from GraphQL Explorer Sandbox (I’m running an Apollo server).

Any ideas as to what this is about?

Many thanks
