Unable to start server with mocks

I am trying to start yoga server with mocks. Just copy-pasting example from the docs doesn’t work:

import { GraphQLServer, MockList } from 'graphql-yoga'

const typeDefs = `
  type Query {
    hello(name: String): String!
    listOfStrings: [String]
  }
`

const mocks = {
  Query: () => ({
    hello: () => 'Hello World',
    listOfStrings: () => new MockList([2, 6]),
  }),
}

const server = new GraphQLServer({ typeDefs, mocks })
server.start()

And got an Error: No schema defined, at /node_modules/graphql-yoga/src/index.ts

@checkmatez @merelinguist I dont know if there is bug or feature, but you have to pass at least empty resolvers.

import { GraphQLServer, MockList } from 'graphql-yoga'

const typeDefs = `
  type Query {
    hello(name: String): String!
    listOfStrings: [String]
  }
`

const mocks = {
  Query: () => ({
    hello: () => 'Hello World',
    listOfStrings: () => new MockList([2, 6]),
  }),
}

const server = new GraphQLServer({ typeDefs, resolvers: () => true, mocks })
server.start()
