Make sure you import correct typeDef and revolvers in types/index.ts and resolvers/index.ts Sometimes it import model in types/revolvers, That cause the issue for me

You should post the relevant code samples directly into your question, because links can be dead in the future. One thing i have noticed is that you are missing closing } in your typeDefs. Example from auth.js

const { gql } = require("apollo-server-express");

module.exports = gql`
type Query {
    me: String!
`;
