res => {

if (res && res != null) {

const array = [];

const ids = [];

this.dynamicFormData.forEach(function (item) {

if (array[0] == null) {

array.push(JSON.parse(item.response));

}

else {

var mainArray = JSON.stringify(array[0]);

for (let key in JSON.parse(mainArray)) {

if (JSON.parse(mainArray).hasOwnProperty(key) == JSON.parse(item.response).hasOwnProperty(key)) {

}

}

console.log(array);

array.push(JSON.parse(item.response));

ids.push(item.id);

}

});

this.dynamicFormResponses = array;

this.dynamicFormResponsesId = ids;
