Cannot deserialize the current json object because(e.g.{"name":"value"}) into type because the type requires a json array (e.g.[1, 2, 3])

error :

Error converting value "38322c46-2f73-42b7-9244-39081991d46f" to type 'Myproject.data.Core.divisionIds'. Path 'conversations[0].divisionIds[0]', line 1, position 220.

What I have tried:

Json

XML

{
  "conversations": [
    {
      "originatingDirection": "inbound",
      "conversationEnd": "2021-03-18T12:39:57.587Z",
      "conversationId": "46f7cda7-ad75-4a1e-b28c-b1c8c01e609e",
      "conversationStart": "2021-03-18T12:39:01.206Z",
      "divisionIds": [
        "aaabbbba-ertw-cldl-2021-547fff22ff33",
        "ddfrgfsc-c3e4-a8f9-b28c-b1c8c01e609e"
      ]
      }]
      }

C#

public class conversations
    {
        public List<divisionIds>  divisionIds { get; set; }

    }

    public class divisionIds
    {
        public string divisionId { get; set; }
    }

C#

responseHeader = JsonConvert.DeserializeObject<ConversationsList>(response.Content);
                if (responseHeader.totalHits > 0)
                {
                    ConversationsList ConversationList = JsonConvert.DeserializeObject<ConversationsList>(response.Content);
                    InsertConversation(ConversationList);
                }

The divisionIds in the JSON is an array of strings. But you class definitions have it as a single string. Also, I do not think it is a good idea to use the same name for your list as you have for the class.

This is what Visual Studio created from the JSON text above:

JSON

public class Rootobject
 {
     public Conversation[] conversations { get; set; }
 }

 public class Conversation
 {
     public string originatingDirection { get; set; }
     public DateTime conversationEnd { get; set; }
     public string conversationId { get; set; }
     public DateTime conversationStart { get; set; }
     public string[] divisionIds { get; set; }
 }

Start by taking your JSON and running it through an online JSON-to-C# converter, like this one: Convert JSON to C# Classes Online - Json2CSharp Toolkit[^]

What you get are classes that work with that JSON data:

C#

// Root myDeserializedClass = JsonConvert.DeserializeObject<Root>(myJsonResponse);
    public class Conversation
    {
        public string originatingDirection { get; set; }
        public DateTime conversationEnd { get; set; }
        public string conversationId { get; set; }
        public DateTime conversationStart { get; set; }
        public List<string> divisionIds { get; set; }
    }

    public class Root
    {
        public List<Conversation> conversations { get; set; }
    }

As you can see, the Root object contains a collection rather than a single object - because that is what your JSON data is describing!

You can either remove the collection from the source JSON (not recommended) or access the collection to get the actual data object(s).
