The use of null or Nothing in JSON literals sometimes cause error BC30521 #16

Summary

I'm trying to initialize a variable with the JSON literal syntax. When I copy a JSON snippet to VB code, null objects in JSON have compilation errors.

Steps to reproduce

Use the following JSON to initialize a variable:

{
  "columns": {
    "A": {
      "rows": {
        "1": {
          "value": 1
        },
        "2": {
          "value": 1
        },
        null,
        "4": {
          "value": 1
        }
      }
    }
  }
}

Expected behavior

No compilation errors. The type of null is DEFAULT_JSON_OBJECT_TYPE.

Actual behavior

Error BC30521

Workaround

Use an uninitialized JObject or JsonObject to replace null objects.

JsonConstants.vb

Imports Newtonsoft.Json.Linq

Module JsonConstants
    Friend vbNullJsonObject As JObject
End Module
