asp.net-mvc - queryBuilder.js - 如何将 JSON 规则转换为 IFilterRule？

Question

我们将过滤器查询作为 JSON 字符串存储在数据库中

但是，当尝试将其转换为 IFilterRule 时，它​​会引发错误

我检索查询并尝试将其反序列化为 IFilterRule

var includeQuery = JsonConvert.DeserializeObject<IFilterRule>(x.IncludeQuery);
var data = _usedService.Find(id).BuildQuery(includeQuery).ToList();

但它抛出了这个错误，关于我做错了什么的任何想法？
