Invalid api key throwing unhandled Exception.

[sahithiYar]

when an invalid apiKey is sent to the query request of rally api, request.js file in dist folder of rally is throwing unhandled exception.

Below is the code in request.js => dorequestPromise =>

var result = _lodash2.default.values(body)[0];
if (result.Errors.length) {
reject(generateError(result.Errors));
} else {
resolve(result);
}

value of body variable:
{
message:null
status:'401'
url:'/slm/webservice/v2.0/userpermission'
}

so when the values of [0] is being picked, result is containing null and the next line trying to check Errors length on null is throwing exception.

Below is my code / repro code
restApi = rally({
apiKey: apikey, // invalid apikey
apiVersion: "v2.0",
server: "https://rally1.rallydev.com",
requestOptions: {
headers: {
"X-RallyIntegrationName": //correct value which work well with valid apikey
"X-RallyIntegrationVendor": //correct value which work well with valid apikey
"X-RallyIntegrationVersion": "1.0",
}, proxy: proxy //correct value which work well with valid apikey
,jar: true
}
});

restApi.query({
type: 'userpermission', //the type to query
start: 1, //the 1-based start index, defaults to 1
pageSize: 200, //the page size (1-200, defaults to 200)
limit: Infinity, //the maximum number of results to return- enables auto paging
fetch: ['Workspace', 'Name', 'Project', 'ObjectID', 'User'], //the fields to retrieve
scope: {}
}, function (error, result) {
})
