ArgumentException in DiagnosticsHandler with external retry mechanism

See original GitHub issue

Describe the bug I use Polly as a retry mechanism and use the CircuitBreaker to wrap call to CosmosDb. When a request is retried, I got an ArgumentException in the DiagnosticsHandler. It try to add again a “System Info” key in the request’s trace.

Expected behavior Do not throw exception, replace the item in the dictionary.

Actual behavior Code throw an ArgumentException.

Environment summary SDK Version: 3.29.0 OS Version: Linux

Did using base.SendAsync fix the error you were seeing?
