cordova appsFlyer app crash first time

Question

I am working on Ionic app and I am using appsFlyer cordova plugin, but somehow whenever user open app for the first time ( i mean whenever app is installed for the first time in device ) it giving error and other following process breaks.

Error :

2016-04-13 11:38:44.047 WotNow[1730:35993] bool _WebTryThreadLock(bool), 0x7fd5450b4170: Tried to obtain the web lock from a thread other than the main thread or the web thread. This may be a result of calling to UIKit from a secondary thread. Crashing now...

And in xcode it highlight below code as error.

XCODE Error Code :

-(void)onConversionDataReceived:(NSDictionary*) installData {
    NSError *error;
    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:installData
                                            options:0
                                            error:&error];
    if (jsonData) {
        NSString *JSONString = [[NSString alloc] initWithBytes:[jsonData bytes] length:[jsonData length] encoding:NSUTF8StringEncoding];
        [[super webView] stringByEvaluatingJavaScriptFromString: [NSString stringWithFormat:@"javascript:window.plugins.appsFlyer.onInstallConversionDataLoaded(%@)", JSONString]];

    } else {
        NSLog(@"%@",error);
    }
}

I am not much aware of Objective-c and iOS errors so it would be much helpful if anyone can tell me where should i look and what should code should i add to resolve such problem.

Try this

 -(void)onConversionDataReceived:(NSDictionary*) installData {
            NSError *error;
            NSData *jsonData = [NSJSONSerialization dataWithJSONObject:installData
                                                    options:0
                                                    error:&error];
            if (jsonData) {
                NSString *JSONString = [[NSString alloc] initWithBytes:[jsonData bytes] length:[jsonData length] encoding:NSUTF8StringEncoding];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT,0),^{

     [[super webView] stringByEvaluatingJavaScriptFromString: [NSString stringWithFormat:@"javascript:window.plugins.appsFlyer.onInstallConversionDataLoaded(%@)", JSONString]]; 
});

            } else {
                NSLog(@"%@",error);
            }
        }
