Handle non-array/object
JsonElementcases.If the
JsonElementrepresents a string, number, or boolean, it will be ignored. Consider adding a fallback to capture these value kinds:if (element.ValueKind == JsonValueKind.Array) jsonObject[args.Key] = JsonArray.Create(element); else if (element.ValueKind == JsonValueKind.Object) jsonObject[args.Key] = JsonObject.Create(element); +else + jsonObject[args.Key] = element.GetRawText();📝 Committable suggestion
