My PDf files are being fetched correctly with no network error (i’m able to render this pdf in an isolated testing app so it’s not the pdf itself)

**Expected behaviour**  
Render PDF with correct tools from PDF express plus

**Does your issue happen with every document, or just one?**  
Every document (local in public folder), and every hosted pdf link

**Link to document**  
{Provide a link to the document in question if possible}

**Code snippet**

```javascript
import { useRef, useEffect } from "react";
import WebViewer from "@pdftron/pdfjs-express";

const DocumentViewer = () => {
  const viewer = useRef(null);

  useEffect(() => {
    WebViewer(
      {
        path: process.env.PUBLIC_URL + "/pdfjsexpress",
        initialDoc: process.env.PUBLIC_URL + "/pdfjsexpress/demo.pdf"
      },
      viewer.current,
    ).then((instance) => {
    });
  }, []);

  return (
    <div className="">
        <div className="header">React sample</div>
        <div className="webviewer" ref={viewer}></div>
    </div>
  );
};

export default DocumentViewer;

```
