Syntax Error on makeExecutableSchema: Unexpected Name “User” (GraphQL)

Question

I need some help to solve an error on graphql, I can't find anything on this case.

I tried to separate my different schemas and resolvers to make it easier to maintain, but when I use makeExecutableSchema function (from graphql-tools package), a "GraphQLError: Syntax Error: Unexpected Name "User"" error is throw.

So here is the Error :

/Users/thomasblanquet/EIP_Routs/API/routs-api/node_modules/graphql/language/parser.js:153
  throw unexpected(lexer);
  ^

npm ERR! Exit status 1
npm ERR! 
npm ERR! Failed at the [email protected] start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

And here is my code :

For the User schema :

const User = `
User {
  _id: Int!
  username: String!
  email: String!
}

extend type Query {
    users: [User]
}
`;

module.exports = User;

For the resolver (the model is create with sequelize and I'm using Apollo-Server-Express):

const User = require('../../server/models/user')
const Messages = require('../messages');

const resolvers = {
  Query: {
    users(parent, args, context, info) {
      parent.getUsers()
    },
};

module.exports = resolvers;

And finally the code to put the schemas and resolvers together :

const { makeExecutableSchema } = require('graphql-tools');
const resolvers = require('./resolver');
const User = require('./user/schema');

const Query =
`type Query {
  _empty: String
}`;

const Mutation =
`type Mutation {
  _empty: String
}`;

module.exports = makeExecutableSchema({
  typeDefs: [Query, Mutation, User],
  resolvers,
});

I really can't find anything about this kind of problem, thanks for helping me :)

You're seeing that error because you left off the type keyword in your User type definition. It should be:

type User {
  _id: Int!
  username: String!
  email: String!
}

Also be mindful that your resolver is calling getUsers on the root object, which will also probably blow up (I imagine you meant to use your model instead).
