我似乎在解析JSON时遇到了一点麻烦，但不是所有的JSON。我从Shopify中提取数据，当我获取products.json时，它会正确解析。当我得到一个特定的产品时，我得到一个'无效的类类型转换'错误。
在 Delphi XE4中使用dbxjson.pas，我正在学习如何使用它。下面的一些代码取自上一个关于一般使用JSON解析器的问题的答案。
我只是将JSON放入一个memo字段，然后调用parsejson2（memo1.text），它将结果放入memo2。
我正确地获取了JSON，并通过json.parser.online.fr验证了它是正确的
下面是JSON输出，它与我的代码一起工作：
