Having trouble passing JS objects as arguments in ClojureScript/JS interop

Despite me passing in (js-obj "audio" true) or other variants into getUserMedia, i.e. (.. js/window -navigator -mediaDevices getUserMedia (js-boj {"audio" true})), it complains about not having a video or audio constraint: “Failed to execute ‘getUserMedia’ on ‘MediaDevices’: At least one of audio and video must be requested”. What method of passing in the object would work here?
