Access JObject in index failed

[Oceania2018]

When I try to access vaue in items[0], it threw error below:

To reproduce:
make a json string like

{
  "items": [{"p1": 1}],
  "row": 1
}

Then use JObject.Parse(Response.Content) to get a JObject.

Below is my ugly fix, convert string "0" to int 0:

• need to add more logic to check for IList which is obvious choice
• should also cache reflection search results
