Unable to get the local-notification immediately without any delay when a message received from websocket

I am trying to push notification message from webserver to my mobile client using websocket. on my websocket onmessage received event i am showing up a local-notification using the plugin(“nativescript-local-notifications”) here is the code i used

LocalNotifications.schedule([{
           id: 1,
           title: 'New Message from websocket' ,
           body: 'Test message',
           ticker: 'The ticker',
           ongoing: true, // makes the notification ongoing (Android only)
           sound: "customsound-ios.wav", // falls back to the default sound on Android
           at:new Date()  //same behaviour when comment out  this line
         }]).then(
             function() {
               console.log("Notification scheduled");
             },
             function(error) {
               console.log("scheduling error: " + error);
             }
         )
       });

using the above code i am getting local-notification 5secs after the websocket onmessage received event. but if i use the same code inside the button tap event i am getting the local-notification immediately. any help or troubleshooting tips is highly appreciated.

Thanks Nicklliev. it works well. after cloned the application deleted my previous version of the application from my device removed the node_modules, platforms and hooks folders rebuild and redeployed the application with run android

@BoobalakannanSubbaiyan the issue is not reproducible on our side when the at key is removed - here you can find a sample project used with nativescript-local-notifications and nativescript-websockets.
