Release Note Description

[riarenas]

This was caused by a mistake while rotating a client secret for the Nethelix Entra application which has already been fixed. I'll use this issue as the root cause for any related failures and to monitor recovery.

[riarenas]

Helix jobs sent while this was ongoing resulted in HTTP 500s when posting the job, with a log similar to:

Microsoft.DotNet.Helix\Sdk\tools\Microsoft.DotNet.Helix.Sdk.MultiQueue.targets(68,5): error : RestApiException`1: The response contained an invalid status code 500 Internal Server Error 

[riarenas]

I'm still seeing these issues. Checking.

[riarenas]

A couple of secrets that depended on the secret that was cycled incorrectly were broken as part of this as well. We have a backlog of older messages that need to be processed first, but I'm starting to see recovery.

[riarenas]

All the fallout from this seems to have been fixed. Closing
