Hi, I've just now finally had a chance to work on this. When running your code, it gets to the line var mail = EsA.Character.Mail.GetHeaders(CharacterID).Execute(); Then goes into your code Mail.cs line 23 @ /// <summary>Return Mail Headers (50 most recent)</summary> /// <remarks>Requires SSO Authentication, using "read_mail" scope</remarks> /// <param name="CharacterID">(Int32) Character ID</param> /// <returns>EsiRequest</returns> public EsiRequest GetHeaders(int CharacterID) { return GetHeaders(CharacterID, null, null); } This calls Mail.cs line 75 @ /// <summary>Return Mail Headers with the specified label</summary> /// <remarks>Requires SSO Authentication, using "read_mail" scope</remarks> /// <param name="CharacterID">(Int32) Character ID</param> /// <param name="Labels">(Int64) Mail Label</param> /// <param name="LastMailID">(Int32) Last Mail ID to include</param> /// <returns>EsiRequest</returns> public EsiRequest GetHeaders(int CharacterID, IEnumerable<long> Labels, int? LastMailID) { var Path = $"/characters/{CharacterID.ToString()}/mail/"; var Data = new { labels = Labels.ToArray(), last_mail_id = LastMailID }; return new EsiRequest(EasyObject, Path, EsiWebMethod.AuthGet, Data); } And fails on line 78 @ var Data = new { labels = Labels.ToArray(), last_mail_id = LastMailID }; Because it looks like you're sending null to the Labels argument of the GetHeaders function, but I'm guessing you can't use ".ToArray()" on a null. Error text: System.ArgumentNullException occurred HResult=0x80004003 Message=Value cannot be null.
