Dear Zendesk,
We are trying to run your package on IOS real device but we are getting the following error.
Can you please advise us on this issue
Thank you

I'm facing the same issue, are there any updates?

[IanWambai]

Same here any updates?

We have android and ios versions of our app. On android it works fine. On Ios we receive this error. We are using the same key for android and ios. Do we need separate keys for android and ios?

Finally i found this solution :

Cause :

PlatformException(channel-error, Unable to establish connection on channel., null, null)

issue from

zendesk
                      .setVisitorInfo(
                    name: 'My Name',
                    phoneNumber: '323-555-1212',
                  )
                      .then((r) {
                    print('setVisitorInfo finished');
                  }).catchError((e) {
                    print('error $e');
                  });

in my case start chat zendesk blocked by

zendesk
                      .setVisitorInfo(
                    name: 'My Name',
                    phoneNumber: '323-555-1212',
                  )
                      .then((r) {
    zendesk.startChat(
                  }).catchError((e) {
                    print('error $e');
                  });

so the solution is separate setVisitorInfo and startChat

 @override
 void initState() {
zendesk
                      .setVisitorInfo(
                    name: 'My Name',
                    phoneNumber: '323-555-1212',
                  )
                      .then((r) {
                    print('setVisitorInfo finished');
                  }).catchError((e) {
                    print('error $e');
                  });
}
}

RaisedButton(
                  child: Text('Start Chat (styled)'),
                  onPressed: () async {
                    zendesk
                        .startChat(
                      iosNavigationBarColor: Colors.red,
                      iosNavigationTitleColor: Colors.yellow,
                    )
                        .then((r) {
                      print('startChat finished');
                    }).catchError((e) {
                      print('error $e');
                    });
                  },
                ),

Thanks

@kharisazhar still the above solution which u provided is not working. Issue still persist for iOS Real device

[theakanfecode1]

Any update on this error please?

[kharisazhar]

@bhagyashreekhatri @theakanfecode1

can you show your code please ?

in my case, i just separte setVisitor info with startZendesk :

or you can try, just set startZendesk : (because visitor info is provided by Zendesk V2 Chat Bot, before connect with agent, zendesk will be ask your name and phone)

zendesk .startChat( iosNavigationBarColor: Colors.red, iosNavigationTitleColor: Colors.yellow, ) .then((r) { print('startChat finished'); }).catchError((e) { print('error $e'); });
