Get pages is not supported while embedding a visual

Hello

We have embedded a single Visual from one or more reports, and we want to be able to change the filters. 

My problem, how do I get a Visual when the embedded report has no pages.

report.getPages().then (function(pages) {

});

Error message: "Get pages is not supported while embedding a visual."

Is there any way to access a visual when not embedding pages in a report?

Thanks!
