..the following error is shown in console.

Hello, which alpha are you using? alpha1? I think we fixed this in a later patch. Can you please confirm that master has the same issue?

OK, using dev-master this specific error is gone, to be replaced with the CMS emitting the following error via the top-right "Growl" message box:

TypeError: 1 t is undefined

...and from the console no error, just valid JSON with a "data" object, and child "readFiles".

Closing in favour of #5535.
