router.popOut() could not open the window - ...

Warnings reference › data-router:popout-blocked

Identifier

data-router:popout-blocked

Raised by

Data Router

Since

1.121.0

What happened

window.open returned nothing (the browser blocked the popup, or the code runs where no window API exists). The call does not throw: it returns a handle with blocked: true and window: null, whose focus()/close() are no-ops.

The fix

Open pop-outs from a user gesture so the browser lets them through, or accept the blocked handle and show the panel in-page instead.

The smallest fix

const h = router.popOut({ url: '?panel=chart', name: 'chart' }); if (h.blocked) showInPage();
