topBarClient.request(settings).then(
function (data) {
console.log("data",data);
showTaskData(data);
if (data.status === 200) {
onSuccess(JSON.parse(data.responseText));
} else {
onFailure(data.status);
}
},
function (response) {
console.log("error", response);
onFailure(response.status);
}
);
onFailure is working but not able to get the error out
Is there a way to test this locally?
console.log works fine, if it's not working then it is not getting called probably due to some exception in the line above console.log.
If you face any problem you can render html component like div to dislplay the text for debugging purpose.

I am trying to use react-native-fbsdk in my react-native app. It was working fine untill yesterday. But, today it gives a weird error stating RCTJSONStringify() encountered the following error: Invalid type in JSON write (NSURL).
RN v0.42.0
Here is my code:
_fbAuth(error, result) {
if (error) {
console.log("error");
alert("login has error: " + result.error);
} else if (result.isCancelled) {
console.log("login cancelled");
alert("login is cancelled.");
} else {
AccessToken.getCurrentAccessToken().then((data) => {
console.log("login success");
console.log(data.accessToken.toString());
let accessToken = data.accessToken;
alert(data.accessToken.toString());
const responseInfoCallback = (error, result) => {
if (error) {
console.log(error);
} else {
console.log(result);
}
}
const infoRequest = new GraphRequest(
'/me',
{
accessToken: accessToken,
parameters: {
fields: {
string: 'email,name,first_name,middle_name,last_name'
}
}
},
responseInfoCallback
);
// Start the graph request.
new GraphRequestManager().addRequest(infoRequest).start();
});
}
}
render() {
console.log("in new render");
return (
<View style={styles.container}>
<LoginButton
publishPermissions={["publish_actions"]}
onLoginFinished={this._fbAuth}
onLogoutFinished={() => alert("logout.")}/>
</View>
);
}
The error information printed in debugger:
I get the above error while calling the graphAPI in the function responseInfoCallback. Any ideas what is happening ?
Update 1:
This error happens only when remote debugger is turned on!! Else it is not happening. But without remote debugger, I cannot proceed with developing the app. Are there any other methods to see log statements of react-native app other than remote debugger ?
Update 2:
The RCTJSONStringify() error happens only behind proxy. And also https fetch calls does not work under proxy. I tested in an open network, it works fine. I guess, it is to add some proxy information to RN app. I think it is related to APP transport security
If you turn the debugger off, you can see the proper error in the XCode console. Access it from Xcode menu View/Debug Area/Activate console, if it's not enabled automatically.
I am developing an App in Ionic/Cordova with Login over Facebook. Before showing the "Login-Page" I would like to check if the user is already connected.
The following getLoginStatus check works as expected in the iOS Simulator. When testing on the actual device, the getLoginStatus callback does not get fired.
facebookConnectPlugin.getLoginStatus(
function (response) {
if (response.status == "connected") {
set_tokens(response);
$location.path('/tab/person/me/events');
}
},
function (response) { alert(JSON.stringify(response)) }
);
Already set the Facebook-App to public and verified the App-Id.
Can anybody give a reason for the described behaviour?
I have the following implementation for Facebook login using facebookConnect Plugin.
facebookConnectPlugin.getLoginStatus(
function(response){
if(response.status == "connected"){
//do something, for example share or redirect
}else{
facebookConnectPlugin.login(["basic_info"],
function(success) { /*do something...*/},
function(error) {
//handle error
});
}
}, function(error) {
// handle error
})
}
If you still have errors, try to log the error and success events to see what is happening. This implementations works in a controller.
I'm getting a 409 on PUT, POST and DELETE actions.
I have successfully created a database and have PUT one document successfully ONCE. I have tried local and "normal" documents. I haven't spend any focus on revisions but think it has to do with this. I only want to save and update this one JSON string in my app - thats it.
It's like I have created this one document to stay forever :-)
Will sample code help? I'm really only using Angular's $http.
On a side note: I need a save mechanism in phonegap that is html5 cache-clear resistent.
You need to check if your document exists first before you update it. that's why it worked the first time and not the second.
config.db.get( "myDocumentID", function(error, doc) {
if (error) {
if (error.status == 404) {
//document does not exist insert it
config.db.put( "myDocumentID", myDocument, function(error,ok) {
if(error) { alert( "error" + JSON.stringify( error ) } else {
alert("success");
}
} )
} else {
alert( "error:" + JSON.stringify( error ) )
}
} else {
//update your document
doc.my_new_key = "value";
config.db.put( "myDocumentID", doc, function(error, ok) {
if( error ) { alert( "error:" + JSON.stringify( error ) ) } else {
alert("success");
}
} );
}
} )
I have below script in asp.net mvc:
$.ajax({
url: "/MyController/MyAction/",
type: 'POST',
data: $("#Myform").serialize(),
success: function () {
// Do something
},
error: function () {
// Do something
},
complete: function () {
// Do something
},
beforeSend: function () {
// Do someting
}
});
This script calls to an action in the controller. The controller performs some actions and sometimes things go ok or not. If things went ok, I want success and complete options in the script get executed.No problem until here, but if in the controller there is an error or something I want to tell the script: "hey, there is an error!" and then the error option in the script to be executed. How to do this? Do I have to return something from the controller to the script to indicate an error has been generated in order to error option in the script gets executed?
Set the HTTP status code to 4xx or 5xx in the controller.
That will make you end up in the error callback.
As far as the AJAX request goes an error is an transfer/network error getting the page.
If you want to return an error either return it in the data then parse that and execute the error function inside the success part if you detect an error. Or as, Johan says, return an HTTP error code from the server.
Use try catch in your action like,
public ActionResult Sample()
{
try
{
return Json(new{status="success"},JsonRequestBehavior.AllowGet);
}
catch(Exception ex)
{
return Json(new{status="failed"},JsonRequestBehavior.AllowGet);
}
}
In your ajax call success check with condition like,
if(data.status=='success')
{
alert('All Happies');
}
else
{
alert('error came');
}
Hope this helps.
I am using MVC to pass JSON data to JsTree and show a hierarchical view of information.
Everything is working just fine, however, there are times when the user does not have access the the data or for some reason the MVC action throws an exception:
In these cases, the action passes a JSON error message and sets the HttpStatusCode to NotAccepted or InternalServerError.
However the jsTree's sinner keeps spinning and I don't seem to find a way to make it stop and show the error message.
Has anyone solved this issue before? How can one does error handling when using JsTree's JSON data plugin?
UPDATE:
I figured out how to capture the error:
$("#jstree1").jstree({
"json_data": {
"ajax": {
"url": serviceUrl,
"data": function (n) {
return { pid: n.attr ? n.attr("id") : "" };
},
"error": function (x, s, r) { var err = $.parseJSON(x.responseText); if (err!="") { alert(err); } }
}
}
It seems that JsTree does get the MVC http statusCode and the error, now I need to figure out how to tell the JsTree to stop waiting and remove the spinner image!
I am also looking for a good way of showing the error in JsTree, or should I manage the error message outside of it?
I've solved this problem.
Just a note- the code example above for handling ajax call errors is incorrect, please see a complete example below:
$('#YourTree').jstree({
"json_data": {
"ajax": {
"url": "/Controller/Action",
"data": function () {
return { Parameter1: "Value1", Parameter2: "Value2" }
},
"type": "POST",
"dataType": "json",
"error": function (jqXHR, textStatus, errorThrown) { $('#YourTree').html("<h3>There was an error while loading data for this tree</h3><p>" + jqXHR.responseText + "</p>"); }
}
}
});
And in the actual action, you need to set the http response status code to 1 and write the error. e.g.
Response.StatusCode = 1
Response.Write("Error you want to go into jqXHR.responseText here");
Enjoy :)
Maybe you should look into handling this error a layer above the .jstree. Maybe by handling the window.onerror event you can achieve this. In here you could call a function that will rebuild the tree or something? Be sure to include this script as the first one in your page.
<script type="text/javascript">
window.onerror = function(x, s, r){
alert('An error has occurred!')
}
</script>
