Unknown function 'translate3d'

Question

Sass gives me an error: Unknown function 'translate3d', highly confused on why sass doesn't recognise it.

Code, if it can be of any use:

.app-cursor {
z-index: 1000;
border-radius: 50%;
width: 80px;
height: 80px;
border: 1px solid black;
pointer-events: none;
overflow: hidden;
position: fixed;
transform: translate3d(0, 0, 0);}
