Ensuring the validation of checkboxes using the Bootstrap framework

I am currently working on validating checkboxes using JavaScript. If the validation fails, I want to display a div with the class invalid-feedback below the checkboxes. However, when I add the invalid-feedback class to my div, it simply disappears.

<div class="form-check form-check-inline">
    <input class="form-check-input" type="checkbox" id="gridCheck1" oninput="validateCheckbox()">
    <label class="form-check-label" for="gridCheck1">
        checkbox1
    </label>
</div>

<div class="form-check form-check-inline">
    <input class="form-check-input" type="checkbox" id="gridCheck2" oninput="validateCheckbox()">
    <label class="form-check-label" for="gridCheck2">
        Checkbox2
    </label>
</div>

<div id="checkboxIdError">I NEED TO ADD THE invalid-feedback CLASS HERE</div>
