Cannot read property 'la' of undefined

I try to use overlayLibrary for popover action.
Get the error message below, can anyone help?
"Cannot read property 'la' of undefined" 
<aura:component >    
    <lightning:overlayLibrary aura:id="overlayLib"/>
    <lightning:button name="popover" label="Show Popover" onclick="{!c.handleShowPopover}"/>    
    <div class="mypopover" onmouseover="{!c.handleShowPopover}">Popover should display if you hover over here.</div>
</aura:component>

// Controller
({
    handleShowPopover : function(component, event, helper) {
        component.find('overlayLib').showCustomPopover({
            body: "Popovers are positioned relative to a reference element",
            referenceSelector: ".mypopover",
            cssClass: "popoverclass"
        }).then(function (overlay) {
            setTimeout(function(){ 
                //close the popover after 3 seconds
                overlay.close(); 
            }, 3000);
        });
    }
})

// app
<aura:application >
    <c:Popover_OneStop />
</aura:application>

lightning: overlayLibrary is not supported in the lightning application. It's supported only on salesforce lightning experience Lightning, Console, Communities .


If you wanted to test it create a component tab or add the component to the lightning experience and test and it not with the app
