Fix NullReferenceException in GetEnrollmentResult for null DCV email#9
Merged
Conversation
The condition for adding DCV email entries to the cnames dictionary was inverted (string.IsNullOrEmpty instead of !string.IsNullOrEmpty), causing cnames.Add(null, null) and an ArgumentNullException on every enrollment where CSC returned a DcvDetail with email=null (typical for EMAIL DCV orders that have actionNeeded=N, and for CNAME-only DCV). Inverts the condition and adds a ContainsKey guard to mirror the existing CName branch.

Summary
Fixes an ArgumentNullException (Value cannot be null. Parameter 'key') thrown from RequestManager.GetEnrollmentResult on every CSC enrollment where CSC returns a DcvDetail with email=null (typical for EMAIL DCV orders that come back with actionNeeded=N, and for CNAME-only DCV).
The condition for adding DCV email entries to the cnames dictionary was inverted: when dcv.Email was null, the original code entered the branch and called cnames.Add(null, null), throwing immediately. The new condition skips null/empty values (matching the intent) and adds a ContainsKey guard symmetric to the existing CName branch above.
