为什么Apache NiFi的ValidateRecord无法捕获无效的枚举？

Question

我正在尝试让Avro架构注册表强制执行enum类型。这是我的avro架构的相关部分：

...
{
  "name": "profileImageSource",
  "type": {
    "name": "ProfileImageSource",
    "type": "enum",
    "symbols" :  ["BASE64", "URL", "S3"]
  },
  "doc": "One of three options as to how the profile image will be provided: BASE64, URL, or S3."
},
...

...但是，当我使用ValidateRecord时...它没有 - 我可以为profileImageSource字段添加任何内容，并且它已被接受。

更新（额外信息）

Strict Type Checking无效（无论是真还是假，结果都相同）。

如果要重现此内容，可以使用此avro架构和示例数据：

模式

{
  "type": "record",
  "name": "CustomerRecord",
  "fields": [{
      "name": "identifier",
      "type": "string"
    },
    {
      "name": "profileImageSource",
      "type": {
        "name": "ProfileImageSource",
        "type": "enum",
        "symbols" :  ["BASE64", "URL", "S3"]
      },
      "doc": "One of three options as to how the profile image will be provided: BASE64, URL, or S3."
    },
    {
      "name": "profileImageData",
      "type": "string",
      "doc": "A profile image of the customer."
    }
  ]
}

数据

{
  "identifier": "CUSTOMER-UNO",
  "profileImageSource": "Cheese",
  "profileImageData": "https://google.com"
}

有什么想法吗？谢谢！
