Solution to the problem was to add labels for the inputs but hidden by
CSS
/* Fix to pass Lighthouse: */
.label-hidden {
    position: absolute;
    height: 1px;
    width: 1px;
    clip: rect(1px,1px,1px,1px);
    border: 0;
    overflow: hidden
}
Another solution to the problem:
/* Fix to pass Lighthouse: */
label-hidden { 
    position: absolute; 
    top:-1000px; 
    left:-1000px; 
}
