Description

[Description of the issue]
I use the default example of PuppeterSharp for Generate PDF Files and i got an error like title said.
When I look into the code, my code fails when using await browserFetcher.DownloadAsync();
Specifically when the code calls await _customFileDownload

Complete minimal example reproducing the issue

I already put my api in Azure Functions Linux https://htmltopdffunclinux.azurewebsites.net/api/converted
Just call an api with URL as a request body
You can use postman for this

E.g.

        private async Task<byte[]> ConvertHtmlToPdf(string url)
        {
            try
            {
                using var browserFetcher = new BrowserFetcher();
                await browserFetcher.DownloadAsync();
                // from this code, i get the error failed to download chrome for linux
                await using var browser = await Puppeteer.LaunchAsync(new LaunchOptions { Headless = true });
                await using var page = await browser.NewPageAsync();
                await page.GoToAsync(url);
                await page.EvaluateExpressionHandleAsync("document.fonts.ready");
                var bytes = await page.PdfDataAsync();
                return bytes;
            }
            catch (Exception)
            {
                throw;
            }
        }

// Act
...

// Assert
...

Yes. Can you share the inner exception and the stack trace?

Here is my inner exception

{ "Value": "One or more errors occurred. (An exception occurred during a WebClient request.)", "Formatters": [], "ContentTypes": [], "DeclaredType": null, "StatusCode": 400 }

If you want to run that in azure functions you will have to use a docker image. You won't want to download the browser on every run.

This is quite an old post but it should help you get started https://www.hardkoded.com/blog/running-puppeteer-sharp-azure-functions

I had the same problem and it was because it couldn't write the downloaded file to the download location.
Try setting the CacheDir folder to a writeable location. Here's an example.

using var browserFetcher = new BrowserFetcher
{
    CacheDir = "/tmp"
};
var download = await browserFetcher.DownloadAsync(BrowserTag.Stable);

You will need to read the download.GetExecutablePath() to find the chrome driver has been downloaded to.
