TypeError: Cannot read properties of null (reading 'location') #259
Description
Hi,
We recently updated to "ng2-pdfjs-viewer" version "18.0.0". After this update, we started encountering an error. We open the PDF viewer in a dialog window, and for the first time, it works correctly. However, when we open the dialog with the PDF viewer again, it starts throwing an exception. Eventually, it displays the PDF properly.

Every time we open dialog with PDF viewer again, number of exception raise up:
After we refresh the page with F5, the first opening of the PDF viewer in dialog window is again without errors.
In the previous version, it was OK. Is anyone else encountering this issue too?
Usage:
<div style="width: 100%; height: 100%; min-height: 750px">
<ng2-pdfjs-viewer #pdfViewer></ng2-pdfjs-viewer>
</div> @ViewChild('pdfViewer', { static: true }) pdfViewer: any;
@Input() set document(value: Observable<Blob>) {
if (this.pdfViewer && value) {
value.subscribe((response) => {
try {
this.pdfViewer.pdfSrc = response;
this.pdfViewer.refresh();
} catch (error) {
console.error(error);
}
});
}
}
