This is my schema. But I'm not able to insert data to bicepsExcercise image Please help me with Controllers to add some data in Biceps Excercise. When I try to insert the Data directly by accessing excercise nothing happens. I want to insert data in bicepsExcercise and in Image field

const mongoose = require('mongoose')

const DataModel = new mongoose.Schema({
    excercise: [{
        bicepsExerciseImage: {
            image: {
                type: String
            },
            bicepsExercise: {
                type: {
                    type: String
                },
                name: {
                    type: String,
                },
                videoUrl: {
                    type: String,
                },
                time: {
                    type: String,
                    default: "Null"
                },
                image: {
                    type: String,
                }
            },
        }
    }]
})

module.exports = mongoose.model('DataModels', DataModel)
