我正在做一个程序，该程序会自动反序列化给出的JSON字符串，问题是我收到了 JSON 和 ObjectMapper 在Java对象中。

  "Trazado": [
    {
      "Historial": [
        {
          "Longitude": 454353,"Latitude": 32423
        },{
          "Longitude": 454353,"Latitude": 32423
        }
      ]
    },{
      "Historial": [
        {
          "Longitude": 454353,"Latitude": 32423
        }
      ]
    }
  ],

程序显示此异常：

com.fasterxml.jackson.core.io.JsonEOFException: Unexpected end-of-input in field name

我定义的类与在https://www.jsonschema2pojo.org/
