New headless chrome crashes when passing "--single-process"

[danielgindi]

Description

When passing --single-process - the headless chrome crashes. It worked before the new headless version.

Complete minimal example reproducing the issue

Complete means the code snippet can be copied into a unit test method in a fresh C# project and run.
Minimal means it is stripped from code not related to reproducing the issue.

E.g.

                                  var browser= await PuppeteerSharp.Puppeteer.LaunchAsync(new PuppeteerSharp.LaunchOptions
                                  {
                                      Args = new string[] {
                                          "--single-process", // Less processes -- Currently crashes chrome
                                      },
                                      Headless = true,
                                  });

.

Expected behavior:

chrome.exe should prevail.

Actual behavior:

chrome.exe crashes.

Versions

15.0.0, 15.1.0
.NET 7.0

Additional Information

When calling the new chrome.exe from cmd line with --single-process - it also crashes.

I think that --single-process was more a chromium flag than a chrome one. You could try using HeadlessMode = HeadlessMode.Shell to use the legacy browser or use the SupportedBrowser.Chromium instead of Chrome.

Oh so we have moved from Chromium to Chrome? I did not even notice. Will the new headless mode work with chromium too?

Yes! Since v11. The new headless mode is prior to Chrome for testing in puppeteer. So I bet it works in chromium. That flag god renamed a few times, so that's why I'm not 100% sure.
