mongoose.findOne returns null

I am trying to retrieve todo by id. Code for getTodo service method is as below:

const getTodo = async (id, userId) => {    const todo = await Todo.findOne({ id: id, userId: userId });    return todo;  };  

code from router which acts as a controller is as below:

router.get("/:id", tokenValidation.validate, async (req, res) => {    const serverResponse = { ...defaultResponse };    try {      const decodedToken = jwt.decode(        req.headers.authorization.split(" ")[1].trim()      );      const getTodo = await todoService.getTodo(req.params.id, decodedToken.id);      serverResponse.status = 200;      serverResponse.body = getTodo;      serverResponse.message = "Get todo by id";    } catch (error) {      serverResponse.message = error.message;    }      return res.status(serverResponse.status).send(serverResponse);  });  

But the result is always null, on calling:

http://localhost:3000/api/v1/todos/60422718e9db822de8531e87    {      "status": 200,      "message": "Get todo by id",      "body": null  }  

What is missing in findOne method. Todo with id exists in the collection but is not returned. Please let me know what is missing.

Thanks
