Index out of range when sending github commit status update

[IvanovOleg]

Summary

It seems like argocd notifications 1.2 has a bug when it tries to send github commit status update. I am not sure when exactly it happened (argocd 2.2 update or notifications 1.2), but with argocd 1.6 and notifications 1.1 it was fine. I am using the following configuration (tokens and url were substituted):
