i figured it out. 

referencing https://github.com/mendix/RestServices/issues/60 

Community Commons package was the culprit 
I was running version 7.2.1 
I went to the app store, downloaded and imported version 7.2.0 replacing 7.2.1 

now the program runs with a lots of client errors "Unhandled promise rejection (...)" in the console.
