Drive API files setq sharedWithMe = false causes "500 Internal Server Error"

Question

Is this a mistake or a value is entered incorrectly?

To repeat, go to "Try it!". on google sdk page: https://developers.google.com/drive/v2/reference/files/list#try-it

Try to get the files (you need to authorize); then try entering sharedWithMe = false in the setQ field.

I get the following error (interestingly, sharedWithMe = true successfully):

500 Internal Server Error - Show headers - { "error": { "code": 500, "message": null } } 

Does anyone know why?
