PDF Generation Issue: Footer Images Not Rendering & "Buffer is not defined" Warning

When generating a prescription PDF using @react-pdf/renderer, the footer image fails to render on the deployed Netlify environment, although the header image and a separate signature image (both loaded via URL) render correctly. Additionally, the console displays "Buffer is not defined" and "Not valid image extension" warnings.

The issue initially arose when deploying, as image assets loaded from the frontend's public folder failed to load, reporting "Buffer is not defined". Moving the image assets to the backend and providing direct URLs resolved the header and signature issues, but the footer image issue persists only on the deployed version.

**Netlify when making pdf with images in the public folder(Both Header and Footer not Visible)**

But the Image Path is correct when accessed in browser directly

## Code for when Header is working fine but footer is not

```jsx
// pdfHeader.jsx

import React from "react";
import { View, Text, Image } from "@react-pdf/renderer";
import { styles } from "../styles";
import { environmentUrls } from "../../../constants";

const PDFHeader = () => {
const HeaderImg = `${environmentUrls.file_url}/uploads/document-header.png`;
console.log("HeaderImg", HeaderImg);

return (


{/* Logo or left content */}



);
};
export default PDFHeader;

```

```jsx
//pdfFooter.jsx

import { Image, View } from "@react-pdf/renderer";
import { styles } from "../styles";
import { environmentUrls } from "../../../constants";

const PDFFooter = () => {
const FooterImg = `${environmentUrls.file_url}/uploads/document-footer.png`;
console.log("FooterImg", FooterImg);

return (



);
};

export default PDFFooter;

```

Also Styling is not an issue since FooterImg when replaced with header's link , renders successfully at the footer's place
