Can we just catch the adapter calling failure error details? sample code :
var invocationData = {
adapter : 'UploadAdapter',
procedure : 'uploadImage',
parameters : [uuid, base64Str]
};
WL.Client.invokeProcedure(invocationData, {
onSuccess : uploadImageSuccess,
onFailure : uploadImageFail,
timeout : 60000,
});
I've already tried this:
function uploadImageFail(result){
WL.Logger.debug(JSON.stringify(result);
}
But it was just:
{"invocationContext":null}
My scenario : I'm working on an image uploading adapter (via cordova), and sometimes the uploading may fail. I can easily catch the error message returned from the backend service (which is handled in the uploadImageSuccess function), but it's not easy to retrieve the error logs when the invoking procedure goes wrong.
I am not sure you need to JSON.stringify it the result object. Instead you may want to simply use result.errorMsg.
I also googled, and it produced results on the code that needs to be used... so I would try the options provided in the following articles:
https://www.ibm.com/developerworks/community/blogs/worklight/entry/handling_backend_responses_in_adapters?lang=en
http://www.ibm.com/developerworks/websphere/techjournal/1212_paris/1212_paris.html

I'm trying to run MFP8's push sample app of GitHub. But MFPPush.registerDevice method failed and error message "Failed to register device:" was shown.
function registerDevice() {
WLAuthorizationManager.obtainAccessToken("push.mobileclient").then(
MFPPush.registerDevice(
null,
function(successResponse) {
navigator.notification.alert("Successfully registered");
enableButtons();
},
function(failureResponse) {
navigator.notification.alert("Failed to register");
console.log("Failed to register device:" +
JSON.stringify(failureResponse));
}
)
);
}
I read the MFP8 document and found the note below.
Note: Authenticated notifications are currently not supported in Cordova applications due to a defect. However a workaround is provided: each MFPPush API call can be wrapped by WLAuthorizationManager.obtainAccessToken("push.mobileclient").then( ... );. The provided sample application uses this workround.
The sample code is wrapped by WLAuthorizationManager.obtainAccessToken indeed. But I think MFPPush.registerDevice may be called before 'obtainAccessToken' completes because return value of MFPPush.registerDevice's method is specified as Promise.then() parameter instead of function that call MFPPush.registerDevice.
So I think the sample should be written as bellow,
function registerDevice() {
WLAuthorizationManager.obtainAccessToken("push.mobileclient").then(
function() {
MFPPush.registerDevice(
null,
function(successResponse) {
navigator.notification.alert("Successfully registered");
enableButtons();
},
function(failureResponse) {
navigator.notification.alert("Failed to register");
console.log("Failed to register device:" +
JSON.stringify(failureResponse));
}
)
);
}
}
Could anyone give me some advice about that?
There is additional information. In device log these messages were logged.
Of course, I registered UserLogin security check to MobileFirst Server and UserLogin challengeHandler is created in UserLoginChallengeHandler.js
(I have not changed except bundleId)

When trying to define a Parse Cloud Code server side function to handle login I get 400 Bad Request when I try to call it. When I look at the Parse logs it records the error "Failed with: ReferenceError: user is not defined". But the user is definitely defined!
Below is the definition of the cloud code for LogIn:
Parse.Cloud.define("LogIn", function(request, response)
{
user.logIn(request.params.username, request.params.password,
{
success: function(user)
{
response.success(
{
"success": "Log in successful."
});
},
error: function(user, error)
{
// We must respond with a success in order to access the
// result of the request inside Unity.
response.success(
{
"error": "Log in failed.",
"code": error.code,
"message": error.message
});
}
});
});
From Unity I make this call to the LogIn coud code function:
ParseCloud.CallFunctionAsync<Dictionary<string, object>> ("LogIn", userInfo).ContinueWith (t =>
{
etc.....
}
I get the following error logged in the server side Parse logs when I call the above from Unity using user sashas123 and also student123:
E2014-09-26T17:06:18.001Z] v8: Ran cloud function LogIn with: Input:
{"username":"sashas123","password":"test"} Failed with:
ReferenceError: user is not defined
at main.js:43:5
E2014-09-26T17:38:50.474Z] v10: Ran cloud function LogIn with:
Input: {"username":"student123","password":"test"} Failed with:
ReferenceError: user is not defined
at main.js:43:5
The following snapshot from the Data Browser shows that the above users are definitely defined:
![Parse User class][1]
Is there any issue with calling user.LogIn on the server side through Cloud Code or is this a Unity issue?
It looks like user.logIn should be request.user.logIn :)
I find it's best to handle the case where the function may be called without a logged in user too:
if (request.user.logIn != null)
{
...
}
else
{
response.error("This function must be called with a logged in user!");
}
Hope this help!
I'm working on a mobile prof-of-concept using IBM's Worklight (6.1) to retrieve info via HTTP server (Apache) running on a mainframe (z/OS). I'm using the HTTP adapter procedure to log-on and retrieve data but I so far no success logging on via Worklight HTTP adapter. If I open a browser and provide the 'user:password' headers, the log-in is successful but if I try it via Worklight procedure, the '401 authorization required' error is returned. The HTTP server error log shows:
.. (139)EDC5139I Operation not permitted. (errno2=0x0BE800DB): SAF
authentication failure for "/cgi-bin/itil_v11_main.sh": SAFRunAs
failure on switching SAF UID from Authorization header using
%%CLIENT%% .. user (\xe1\xcb: authentication failure for
"/cgi-bin/itil_v11_main.sh": Password Mismatch
That 'password mismatch' may suggest the 'headers' are not correct? Here's the procedure:
var user_id = 'userid';
var user_psw = 'userpassword';
var loginstring ;
var base64= new com.worklight.customcode.Base64Encoding();
function getITIL() {
loginstring = base64.encode(user_id+':'+user_psw);
var path = '/cgi-bin/itil_v11_main.sh';
var input = {
method : 'get',
headers : {
'Authorization' : 'Basic ' + loginstring
},
returnedContentType : 'html',
path : path
};
return WL.Server.invokeHttp(input);
}
It seems like you've implemented it correctly, however the complaint is on the password, which in your case originates from var base64= new com.worklight.customcode.Base64Encoding();.
Because you do not supply the code that you are using in said class, it's difficult to say what the error is, but that is where you should look at for the cause of your error.
You'll need to provide the class's implementation in order to further debug the question.
I am getting a problem in worklight adapter , In the following http adapter method
,it is showing The mandatory parameter 'action' is missing, returning statusCode as
500 and statusReason as "Internal Server Error". I had given all the user credentials
correctly in adapter xml file, but I don't know why I'm getting this error.
Code:
function actionOnProcessInstance()
{
var param = "/rest/bpm/bfm/v1/process/_PI:9003013d.4387342e.1efe573f.7c20307?action=resume";
var input =
{
method : 'put',
returnedContentType : 'json',
path : param,
};
var response = WL.Server.invokeHttp(input);
return response;
}
In 5.0.5.x, invokeHttp will take any params provided on the path for put and post and place them inside the http body instead of having them remain on the path as query params (as the developer probably intended). This behavior will be updated in an upcoming version but for now there's no way to force these to stay as query params.
I am trying to use the following to do a cross-domain get:
dojo.io.script.get({
url: myUrl,
callbackParamName: "callback",
preventCache: true,
load: dojo.hitch( this, loadFunction ),
error: dojo.hitch( this, function() {
console.log('Error!!!');
})
});
The load function runs fine, however, when the server returns a 404, the error function does not run. Can anyone tell me why?
EDIT
After some investigation, I found that a timeout and handler could be implemented in the following way:
dojo.io.script.get({
url: myUrl,
callbackParamName: "callback",
timeout: 2000
}).then(function(data){
console.log(data);
}, function(error){
alert(error);
});
This uses functionality provided by the dojo.Deferred object.
When accessing server with script tags (that what dojo.io.script.get does), status code and headers are not available.
You may try some other ways to detect a problem, like using a timeout and analyzing a content of a script. The latter is problematic for JSONP calls (like in your example).
I realize this is old but I thought I'd share a solution in case others, like I had, come across this thread.
dojo.io.script is essentially adding a <script/> to your html page. So you can try this:
var script = document.createElement('script');
script.setAttribute('type', 'text/javascript');
script.setAttribute('src', myUrl);
script.onerror = function() {
debugger
}
script.onload = function() {
debugger
}
document.getElementsByTagName('body')[0].appendChild(script);
That way if the script fails to load the onerror event is called.
*This may not work in every instance but is a good start
