Dereference of a possibly null reference.

Possible null reference argument for parameter 'arg2' in 'string Func<TState, Exception, string>.Invoke(TState arg1, Exception arg2)'.

This async method lacks 'await' operators and will run synchronously. Consider using the 'await' operator to await non-blocking API calls, or 'await Task.Run(...)' to do CPU-bound work on a background thread.
