I have integrated Azure Notification Hub with node js using npm package @azure/notification-hubs. Firstly I registered the device and gave it some expression tags. Which is happening successfully. Then by using those tags I am sending sending push notification.
I have tried direct send also.
In the result i am getting status as “Enqueued”.

  successCount: 0,n  failureCount: 0,n  results: [],n  state: 'Enqueued'

Also I am not receiving any notifications on my device.

On the other hand when I use Azure portal to test the send notification I am receiving notifications on my same phone.

This is issue is coming for both android and iOS.

I am using Free version of azure notification hub.

What could be the issue in my integration.

Please guide.
