Puppeteer is not found after Dockerization

My issue arises when running my code on a Linux system within a Docker container. The code, which downloads and launches Puppeteer, works flawlessly on my Windows machine. Here's the relevant snippet:

var browserFetcher = new BrowserFetcher();
var installedBrowser = await browserFetcher.DownloadAsync(BrowserTag.Latest);
var browser = await Puppeteer.LaunchAsync(new LaunchOptions
{
    Headless = true,
    ExecutablePath = browserFetcher.GetExecutablePath(installedBrowser.BuildId)
});

I specifically utilize GetExecutablePath(installedBrowser.BuildId) to avoid hardcoding directories. However, upon building and running the Docker container with an Alpine Linux image, I encounter the following error:

Error: An error occurred trying to start process '/app/Chrome/Linux-124.0.6335.0/chrome-linux64/chrome' with working directory '/app'. No such file or directory

Upon inspecting the container using /bin/sh, I find the necessary files exist:

I'm perplexed by this issue. If further information is required, please let me know. Thank you.

CMD ["dotnet", "PuppeteerProject.dll"]

The long list of dependencies in the third build stage is to support the browser runtime.

🗎 Program.cs

using System;
using System.Threading.Tasks;
using PuppeteerSharp;

class Program
{
    static async Task Main(string[] args)
    {
        await new BrowserFetcher().DownloadAsync();
        var browser = await Puppeteer.LaunchAsync(new LaunchOptions
        {
            Headless = true,
            Args = new string[] { "--no-sandbox", "--disable-setuid-sandbox" }
        });

        Console.WriteLine("Browser launched successfully.");

        await browser.CloseAsync();
    }
}

The example Program.cs will run and then exit. When it exits the container will terminate.

You can, however, get a more persistent container by commenting out the CMD line in the Dockerfile. Then just run it manually.
