An Apollo Server formatError function that avoids "Converting circular structure to JSON" errors
// This is the attribute that continuation local storage uses to hold onto
// the current context. The value comes from https://github.com/othiym23/node-continuation-local-storage/blob/fc770288979f6050e4371c1e1b44d2b76b233664/context.js#L11

// A formatError function that can be used with
// https://www.apollographql.com/docs/apollo-server/features/errors#for-the-client-response
function formatError (err) {
// The continuation-local-storage module attaches a context attribute to
// errors so that the context can be resolved from errors. The attribute
// is enumerable by default and so it gets included in GraphQL error
