JSON result from PipeDrive API does not deserialize

Question

I'll excuse myself in advance for such a long post, fact of the matter is that I have no clue as to where the problem might persist.

I'm working on a program that is required to pull deals - with custom fields - related to a selected organization out of PipeDrive, do some calculations and save the results as a document. Currently it does the following:

1. Query the API for companies using textbox input as keyword.
2. Deserialize the returned JSON in a class generated with JSON2CSharp.
3. Put results in a list.

I've got this part down, it works perfectly. However, when I worked out the second part of the requirements, things get weird. I will elaborate the steps carefully:

1. When an organization is clicked, query the API for deals corresponding to the organization ID and name.

   public List<int> GetOrgDealcodes(string ID, string search)
   {
       List<int> returnlist = new List<int>();
       JsonTextReader reader = new JsonTextReader(new StringReader((string)ReturnObjectsByName(PipeLineNiveau.deals, search, ID)));
       reader.SupportMultipleContent = true;
       JsonSerializer serializer = new JsonSerializer();
       serializer.ObjectCreationHandling = ObjectCreationHandling.Replace;
   
       try
       {
           PipeDriveDeals.RootObject root = serializer.Deserialize<PipeDriveDeals.RootObject>(reader);
           foreach (PipeDriveDeals.data tmp in root.data)
           {
               returnlist.Add(tmp.id);
           }
       }
       catch (JsonException ex)
       {
           Error.TopBar("Deserializing error", ex.Message);
       }
       return returnlist;
   }
   

   ReturnObjectsByName() returns an object containing the JSON response

2. Get details of each of the deal ID's returned.

   public PipeDriveDeals.data GetDeal(string ID)
   {
       PipeDriveDeals.data returnvar = new PipeDriveDeals.data();
       JsonTextReader reader = new JsonTextReader(new StringReader((string)ReturnObject(PipeLineNiveau.deals, ID)));
       reader.SupportMultipleContent = true;
       JsonSerializer serializer = new JsonSerializer();
       serializer.ObjectCreationHandling = ObjectCreationHandling.Replace;
   
       try
       {
           returnvar = serializer.Deserialize<PipeDriveDeals.data>(reader);
       }
       catch(Exception ex)
       {
           Error.TopBar("Error reading deal", ex.ToString());
       }
   
       return returnvar;
   }
   

   ReturnObject() returns an object containing the JSON response

3. Deserialize the returned JSON in a class generated with JSON2CSharp (shown in GetDeal()), meaning this:

4. Process everything in different classes in order to calculate and print results. (this code is irrelevant to the question)

When debugging I see that the request is correct, the returned data is exactly what I expect (as shown in step three) and during deserializing the buffer is filled with said data, but it does not fill the returnvar class with the expected values:

I have no clue why this is happening, after all I have two other interactions with the PipeDrive API that use the exact same methods, have a very similar implementation, and work just fine.

I also noticed that PipeDrive uses randomized strings as identification for custom fields. Some of them tend to start with a number, which means it's not possible to create a variable with the same name (hence the pref_ and __invalid_type__ prefixes). I've attempted to work around this by setting JsonProperty. Could this be the problem and does my workaround not suffice?

Answer 1

I'm late, but it seems fair to post the answer for those that deal with a similar problem: turns out it was a rookie mistake after all. The answer to this mistake was that I tried to fill out the data class rather than the RootObject, which would never work given the hierarchy.
