script.js:22 Uncaught (in promise) TypeError: Failed to execute 'insertAdjacentElement' on 'Element': parameter 2 is not of type 'Element'. code example

Example: Uncaught TypeError: Failed to execute 'insertAdjacentElement' on 'Element': parameter 2 is not of type 'Element'

The second parameter of insertAdjacentElement() should be a html object.
The trick below works :)


var htmlString = `<div class="item clearfix" id="income-${obj.id}">
            <div class="item__description">${obj.descripiton}</div>
            <div class="right clearfix">
                <div class="item__value">${obj.value}</div>
                <div class="item__delete">
                    <button class="item__delete--btn"><i class="ion-ios-close-outline"></i></button>
                </div>
            </div>
        </div>`
 var htmlObject = document.createElement('div');
 htmlObject.innerHTML=htmlString;
 document.querySelector(".income__list").insertAdjacentElement('beforeend', htmlObject);
