What parameter types are supported by Google Endpoints in an API method? -

i can make string, date , long work. if use byte[] error when run endpoints.sh script. can find nothing in documentation lists types supported , errors generated pretty cryptic. i'd little bit of binary (image) data endpoint method. no good:

@apimethod(name = "device.bikeimage.set") public void setdevicebikeimage(com.google.appengine.api.users.user appengineuser,         @named("facebookaccesstoken") @nullable string facebookaccesstoken,         @named("deviceid") string deviceid, @named("bikeimage") byte[] bikeimage)         throws ioexception, oauthrequestexception { }
