LaunchAsync failed on Azure as a Windows/Linux .net core 5 App service

My service is working perfectly locally however when I deploy it on Azure as a Windows .net core 5 Free App service, It throws following exception. My code is shown below.

What is the reason for this? Do I have to install any additional components?

var bf = new BrowserFetcher();
            await bf.DownloadAsync(BrowserFetcher.DefaultChromiumRevision);
            var options = new LaunchOptions
            {
                Headless = true,
                ExecutablePath = bf.GetExecutablePath(BrowserFetcher.DefaultChromiumRevision)
            };

            List<NewsItem> newsItems = new List<NewsItem>();
            using (var browser = await Puppeteer.LaunchAsync(options)) **<= exception thrown here**
            using (var page = await browser.NewPageAsync())
            {
                await page.GoToAsync(url);

Exception: 
System.ComponentModel.Win32Exception (14001): The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail.

I also checked on Linux app service. I end up getting following error when I follow the code here . When I checked the tmp folder it did not have any chrome folders.

Failed to launch browser! /tmp/Linux-884014/chrome-linux/chrome: error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory

I also checked changing the folder to /home/ on linux. This time it downloaded chrome and had all required folders. But now it ended up throwing

Failed to launch browser! Failed to launch browser! /home/Linux-884014/chrome-linux/chrome: error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory

Closed due to inactivity. Feel free to reopen it if needed.

OKay, thanks for your time. I guess I’ll also have to move to some option other than puppeteer.
