Server does not respond with data field in error message if one isnt present on the Error instance in getResult

Line 322 in 5bfddd5

error.data = e.data;

This should likely be

error.data = e.message

Looks like this was fixed in #109 but the implementation is dubious. It assumes that the user is generating the error and adding the 'data' field to that error. It might make more sense that the error message is used unless the error object contains a data field.

So error.data = e.data || e.message

This is unfortunately breaking for many of the tests.
