BrowserFetcher.DownloadAsync(BrowserTag) throws a 404 exception (Chrome)

[Dryvnt]

Description

Attempting to fetch browser with a BrowserTag currently fails. Downloading without an explicit BrowserTag works fine.

I have tested all BrowserTags and reproduced the error for

• Stable
• Latest
• Canary

Complete minimal example reproducing the issue

using PuppeteerSharp;

using var browserFetcher = new BrowserFetcher();
// Resolved URL: https://edgedl.me.gvt1.com/edgedl/chrome/chrome-for-testing/121.0.6167.85/win64/chrome-win64.zip
// Works fine
await browserFetcher.DownloadAsync();
// Resolved URL: https://edgedl.me.gvt1.com/edgedl/chrome/chrome-for-testing/121.0.6167.184/win64/chrome-win64.zip
// Exception: 404
await browserFetcher.DownloadAsync(BrowserTag.Stable);

Expected behavior:

Calling DownloadAsync should not throw an exception when providing an explicit release channel tag.

Actual behavior:

Calling DownloadAsync with an explicit release channel tag throws an exception.

Versions

• Which version of PuppeteerSharp are you using?
  • Experienced on 12.0.0
  • Reproduced on 14.0.0
• Which .NET runtime and version are you targeting? E.g. .NET framework 4.6.1 or .NET Core 2.0.
  • net8.0

Additional Information

As the comments in the example shows, I did some light digging. It seems that the automatic resolution of a build id provides a build id that is not present on the server we attempt to download from (https://edgedl.me.gvt1.com/edgedl/chrome-for-testing/...).

I don't know who is in charge of keeping the builds on that server up-to-date. I understand that it might not be your responsibility, but perhaps something could still be done to attempt to mitigate intermittent failure.

Update:
It seems Google changed where they upload builds to https://storage.googleapis.com/chrome-for-testing-public/, and newer assets are no longer uploaded to the old server. It looks like they wanted to do this in a way that avoids breakage, but shit happens. Regular puppeteer is also suffering. See related issues in comment for more.
