TypeError: Cannot read properties of undefined (reading 'findController')

I'm attempting to implement the find by regex feature as described here: https://pdfviewer.net/extended-pdf-viewer/custom-find

In the showcase code it shows an override method that appears to be attempting to access the finder on the view.

I'm attempting to access the viewer like this:

In previous versions this worked, but with the newest version it's showing this error in the console:

Please advise. Thanks!

Currently I'm implementing a better solution, but in the meantime, let's fix your bug. Luckily, that's easy. With version 21 I've removed PDFViewerApplication from the window object. Polluting the global namespace was a dirty hack that has severe disadvantages.

Nowadays, you can use the PDFNoticationService to get the instance of the PDFViewerApplication:

constructor(notificationService: PDFNotificationService) {
    effect(() => this.PDFViewerApplication = notificationService.onPDFJSInitSignal());
}

Update: I've added the missing constructor to the showcase page.
