i'm using pdf.js and all worked fine until yesterday. Now i get this error:

Uncaught (in promise) Error: PDFPageProxy.getViewport is called with obsolete arguments.
    at PDFPageProxy.getViewport (api.js:964)

I have set a const for the viewport const viewport = page.getViewport(scale);

  /**
   * @param {GetViewportParameters} params - Viewport parameters.
   * @returns {PageViewport} Contains 'width' and 'height' properties
   *   along with transforms required for rendering.
   */
  getViewport({ scale, rotation = this.rotate, dontFlip = false, } = {}) {
    if ((typeof PDFJSDev !== 'undefined' && PDFJSDev.test('GENERIC')) &&
        (arguments.length > 1 || typeof arguments[0] === 'number')) {
      throw new Error(
        'PDFPageProxy.getViewport is called with obsolete arguments.');
    }
    return new PageViewport({
      viewBox: this.view,
      scale,
      rotation,
      dontFlip,
    });
  }

i don't know what's wrong. p.s. i'm not a js master.

I'd guess you are passing a number to that method in scale argument?

It should be an object: try page.getViewport({scale:1}), or {scale:scale} in your case.
