I have clicked on a link to a blog that is still under review (From Stable Intermediate Form - SAP Blogs I clicked on "The Illusion of Control").
I observed a popup of the SAP Id provider (You have been authen...) and I was expecting the system to display the source of the blog, but all I got was an error screen "State Information Lost" with this text in the middle of somewhere:
If you report this error, please also report this tracking number which makes it possible to locate your session in the logs available to the system administrator: ea54b636be
There, I have reported it.
