Came here because I was getting this error when upgrading from v1 to v2:

Deprecated API usage:  PDFDocumentLoadingTask.then method, use the `promise` getter instead.

In short, we now have to explicitly refer to .promise

//V1
const loadPDF = await PDFJS.getDocument(file);
const pages = loadPDF.numPages;


//V2
const loadPDF = await PDFJS.getDocument(file).promise; //<-- simply change it here
const pages = loadPDF.numPages;

The examples have already been updated with this new API usage, just not yet on JSFiddle. @yurydelendik Could you perhaps update all examples on that page with the current code from the examples folder?

the view port error is die to using version 1 way:
var viewport = pdfPage.getViewport(scale, rotate);

change it to use GetViewportParameters :
https://github.com/mozilla/pdf.js/blob/master/src/display/api.js#L158

var viewport = pdfPage.getViewport({scale:scale, rotate:rotate});
