const pdf = require('html-pdf-chrome');

chromeFlags: ['--headless', '--disable-gpu', '--disable-web-security', '--no-sandbox', '--disable-setuid-sandbox']

            let pdfBuffer = await pdf.create(htmlContent, options);
            let buffer = pdfBuffer.toBuffer();

westy92 commented

What is your chrome(ium) version?

dineshkumar14062001 commented

Version 124.0.6367.118 (Official Build) (64-bit)
it is working on my local machine but this error rising in my GCP console.

westy92 commented

Is Chrome installed on your GCP instance? If so, what version?

dineshkumar14062001 commented

we have used GCP serverless, and did not use any instance.

westy92 commented

Html-pdf-chrome requires chrome. You'll likely need a dedicated instance running with a port exposed that your serverless functions can connect to and use.

ok, thank you. I need another question I have printed more than 2000 pages it takes more than 20 minutes, how can I shorten the print pdf?

westy92 commented

If you have one instance of Chrome running, monitor its CPU/memory usage. You may need to limit the concurrency of how many simultaneous PDFs you are generating. If the 2000 pages is a single PDF, consider splitting it up into smaller jobs.
