我正在使用nifi-JoltTransformJson处理器[1.9.2]版本，我有一个输入json，如下所示，其中spec json作为属性。
输入JSON：

{
"Your order":
{
"order_id":2116,
"products":[
{
"productId":"abc",
"productName":"Headphones",
"Cost":500
},
{
"productId":"cad",
"productName":"Laptop",
"Cost":89000
}
],
"total":90000
},
"location":{
"address":"No: 1338 MIG-1 Asian"
}
}

字符串
规格：

[
  {
    "operation": "shift",
    "spec": {
      "location": "counterTop"
    }
    }
]

我在demo-jolt站点链接上收到预期输出：http://jolt-demo.appspot.com/#inception
但在Nifi-1.9.2版本我收到以下错误：
nifi-logs上的错误：

有什么建议来克服这个问题吗？
