I sent 2 and more requests together for rest service and after second response I get an error. Also locally all works great, but on the env I catch exception.
The operation was canceled.
The error acquired: System.ObjectDisposedException: The CancellationTokenSource has been disposed.
at System.Threading.CancellationTokenSource.ThrowObjectDisposedException()
Can anyone suggest something?
