Application Insights Rejecting Exceptions with empty Message

[joshbratt]

When sending exception telemetry through to Application Insights, the request gets rejected with a 400, stating that "Field 'message' on type 'ExceptionDetails' is required but missing or empty."

Repro Steps

1. Perform a call to TelemetryClient.TrackException() with an exception with an empty message.

Actual Behavior

The message is rejected by Application Insights with a 400, requiring the message property to be populated.

Expected Behavior

The message property should not be a required property, or the rejection of the telemetry should be communicated.

var ex = new Exception();
tc.TrackException(ex);

Is the above a repro code for this? Or can you share the snippet to repro.

[joshbratt]

var ex = new Exception("");
tc.TrackException(ex);

It appears to occur when the message parameter is empty or whitespace.
