TypeScript definition missing for error passed to formatError

[dandrei]

Hey everyone,

The error parameter sent to the formatError function (from the config of ApolloServer) is missing TypeScript definitions.

It seems possible that we need to specify a more specific type signature here:

apollo-server/packages/apollo-server-core/src/graphqlOptions.ts

Line 34 in b89de26

formatError?: Function;

Thoughts?

formatError?: (error: GraphQLError) => GraphQLFormattedError;
