Create filtered list view in Calendar using JavaScript/JSOM

I am attempting to create a filtered list view in a Calendar. It is creating everything as appropriate, but not creating the filters. It believe it's my CAML. My goal is to filter by a choice column named "Approval Status" with a value of "Approved":

    function createCalendarView() {

        var currentcontext = new SP.ClientContext.get_current();
        var hostcontext = new SP.AppContextSite(currentcontext, hostweburl);
        var context = SP.ClientContext.get_current();           
        var hostweb = hostcontext.get_web();
        var listCollection = hostweb.get_lists();
        var list = listCollection.getByTitle('Calendar');

        // Create Approved PTO View
        //get the view collection to add the view
        var viewcollection = list.get_views();
        //create a viewinfo with the view properties
        var viewInfo = new SP.ViewCreationInformation(); //create multiple views
        viewInfo.set_title("MYVIEW"); //set the title
        viewInfo.set_viewTypeKind(524288);
        viewInfo.set_setAsDefaultView(true); //set the view to default
        var camlQuery = new SP.CamlQuery();
        camlQuery.set_viewXml('<View><Where><Eq><FieldRef Name="Approval Status"/><Value Type="Text">Approved</Value></Eq></Where></View>');
        viewInfo.set_query(camlQuery);
        //add the view to the view collection
        viewcollection.add(viewInfo);


        //load the view collection
        context.load(viewcollection);
        context.executeQueryAsync(onCalendarViewCreationSuccess, onCalendarViewCreationFail);
    }
