无法在StringReader的START_OBJECT标记中反序列化java.util.ArrayList的实例

Question

无法从java.util.ArrayList令牌中反序列化START_OBJECT的实例：

at [Source: java.io.StringReader@3f680180; line: 1, column: 24966] (through reference chain: com.example.warrantycompass.model.AllProductsResponse["result"]->com.example.warrantycompass.model.Categories["Categories"]->java.util.ArrayList[2]->com.example.warrantycompass.model.ProductCategory["subcategories"])

Json回复：

AllProductsResponse：
