Convert PNG to PDF via server code

Need help Plugins
1

Has anyone achieved a success in converting a PNG to PDF via backend workflow in bubble?
I have a code but cannot properly execute it, nor I receive an error. I assume saving can be a problem but to be honest, I am not sure how to grab the error.

Any experience there?

const { PDFDocument, rgb } = require(‘pdf-lib’);
const fs = require(‘fs’);

async function pngToPdf(pngFilePath, outputPdfPath) {
const pdfDoc = await PDFDocument.create();
const pngImageBytes = fs.readFileSync(pngFilePath);
const pngImage = await pdfDoc.embedPng(pngImageBytes);
const pngDims = pngImage.scale(1);
const page = pdfDoc.addPage([pngDims.width, pngDims.height]);
page.drawImage(pngImage, {
x: 0,
y: 0,
width: pngDims.width,
height: pngDims.height,
});
const pdfBytes = await pdfDoc.save();
fs.writeFileSync(outputPdfPath, pdfBytes);
}

const pngFilePath = ‘DO A SEARCH FOR FILE INPUT’;
const outputPdfPath = ‘DO A SEARCH FOR FILE OUTPUT’;
pngToPdf(pngFilePath, outputPdfPath);

Pretty sure it has something to do with this:

I went with external API for something similar. My use case was to convert any image (jpeg/jpg/png) to SVG.
You can also have custom AWS function → create API → Use in Bubble.

@animisha45 So essentially you mean I should set up an endpoint that would do the work for me, correct? To which I will send the file and in response get the new format.

I meant third-party services that will convert and send you the required output.
