On the server side I have a model and a controller to execute the POST action. However it is giving results of 404.

model would contain array of subdocuments. for example **

[AnswerSchema]
{answer: String,
 index: Number}
[QuestionsSchema]
{question: String,
 answers: [AnswerSchema],...}
[QuizSchema]
{questions:  [QuestionSchema],...}

**

in the controller side it would with an aysnc function

**

const newQuiz = new Quiz({
            questions: req.body.questions
});
        
const savedQuiz = await newQuiz.save();

**

but while using Postman it wouldn't execute the post and give a 404 page. do I need to have any "push" for the questions in the controller side? or is there a hight possibility that there is something wrong with the data tested in postman?
