Error: Uncaught (in promise): TypeError: Cannot read property 'read' of null

See original GitHub issue

Hello, first time submitting an issue for this library!

I am seeing this error in the console anytime I change the value of src through input binding.

TypeError: Cannot read property 'read' of null

Here’s the basic setup I have:

<input #file type="file" (change)="updateFile(file)">

<div *ngIf="pdfSrc" class="pdf-viewer-container">
    <p>Preview</p>
    <ngx-extended-pdf-viewer 
    [src]="pdfSrc" 
    [useBrowserLocale]="true" 
    height="250px"
    zoom="25%"
    [showSidebarButton]="false"
    [showFindButton]="false"
    [showPagingButtons]="false"
    [showZoomButtons]="false"
    [showPresentationModeButton]="false"
    [showOpenFileButton]="false"
    [showPrintButton]="false"
    [showDownloadButton]="false"
    [showBookmarkButton]="false"
    [showSecondaryToolbarButton]="false"
    delayFirstView=1000>
    </ngx-extended-pdf-viewer>
</div>

When the value of pdfSrc changes, I see the error above in the console. The PDF still changes however!

How do I change the file being displayed without this error being printed?

Let’s close the ticket. I suppose it’s like you, @g3344, say: it used to be a common bug, but I’ve managed to solve it.
