Error in Standard Fiori-App Git-enabled CTS (gCTS)

A question for all the happy people implementing gCTS Fiori-App before. :)

So i implemented the app on our 1909 system with SAPUI 754 0002 and get a kind of error when starting the app.

So you see there is a bit of the Fiori-Application on the bottom.

Console:

I also searched notes in the support portal and implemented the central gCTS note. I debugged the app a bit but don't know if i missed something which i don't see in gCTS documentation.

So are there any gCTS early adopter?
