ERROR "Cannot return null for non-nullable field Todo.id"

I am getting non-nullable error for the below code, everything looks fine

const mongoose = require('mongoose');


mongoose.connect('mongodb://localhost/test',{
useUnifiedTopology: true,
useNewUrlParser: true,
})
.then(() => console.log('DB Connected!'))
.catch(err => {
console.log('DB Connection Error: ${err.message}');
});


const Todo = mongoose.model('Todo', {
    text: String,
    compelte: Boolean
});




//Mutation: Need a String Compulsory 

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

  type Todo{
      id: ID!
      text: String!
      done: Boolean!
  }

  type Mutation{
      createTodo(text: String!): Todo 
      updateTodo(id: ID!, complete: Boolean!): Boolean
      removeTodo(id: ID!): Boolean
  }

`;

const resolvers = {
  Query: {
    hello: (_, { name }) => `Hey! ${name || 'World'}`,
    todos: () => Todo.find()
  },

  Mutation:{
      createTodo: async(_,{text}) => {
          const todo = new Todo({text, done: false});
          await todo.save(); // saving the todo to the database using .save()[returns promise] and we await to get it saved on to the database 
        //   return JSON.parse(JSON.stringify(todo)) ;
          return todo;
      },
      updateTodo: async(_,{id, compelte}) => {
        await Todo.findByIdAndUpdate(id, {complete});
        return true;
      },
      removeTodo: async(_, {id}) => {
        await Todo.findByIdAndRemove(id);
        return true;
      }
  }

}

You must add .lean() after .find()

const found = await User.find().lean() // it worked for me 🚀🚀
