Adding these lines seems to fix the code for me:
const bytes = new Uint8Array( pdfBytes );
const blob = new Blob( [ bytes ], { type: "application/pdf" } );
const docUrl = URL.createObjectURL( blob );
setPdfInfo( docUrl );
Or use it directly:
return <iframe src={docUrl} type="application/pdf" />

What I did and worked: I added a reference to the iframe instance:
import React, { useState, useEffect, useRef } from 'react';
const LoadPDF = () => {
...
const viewer = useRef(null);
const modifyPDF = async () => {
...
};
return (
<>{<iframe title="test-frame" src={pdfInfo} ref={viewer} type="application/pdf" />}</>
);
}

r/reactjs on Reddit: Best library for showing a pdf in react
December 2, 2022 -
Hey, I wanted to find out a library in react which can display a pdf from a url. So far I have tried react-pdf from wojtekmaj, it works just fine but I wanted a free library which can provide toolbars also. Let me know if you know any library or a way to build it.
Thanks

If you don't need direct control over the PDF in any way, then just use an IFrame. It'll make the browser use their default viewer, which is generally a pretty decent one. There's also one made by Mozilla ( PDF.js ), but any PDF viewer is going to be pretty heavy in terms of code size.
