//post api

const post = new Post({
        navigation: req.body.navigation
    });
    response = {
        message: 'success',
        uuid: req.body.uuid
    }
    try {
        const savedPost = await post.save()

Answer

Just try to create a schema with an empty object like:

Schema

const PostSchema = mongoose.Schema({
    navigation: {}  
})

so you can add multiple elements. But your data completely depends on what you are sending in your API request.
