Failing Test(s)

• Microsoft.AspNetCore.Identity.Test.IdentityUIScriptsTest class

Error Message

The details here and below are all extracted from the Helix console log. Build logs only show that the work item timed out on the Helix agent. That's because we have a RetryHandler that attempts to download multiple resources from a CDN multiple times with the standard (100 second) HttpClient timeout.

System.Threading.Tasks.TaskCanceledException : The request was canceled due to the configured HttpClient.Timeout of 100 seconds elapsing.
---- System.TimeoutException : A task was canceled.
-------- System.Threading.Tasks.TaskCanceledException : A task was canceled.

Ok with skipping this on mac 10.15 always, this is just checking that we have the right sha hashes on our script tags, so as long as this runs on at least one queue, that is sufficient
