Facebook 脸谱营销API-相似受众创建-可以'；不要创建一个相似的副本

我正在通过Facebook API创建外观相似的自定义受众，但当我尝试从同一种子创建第二个受众时，我不断收到以下错误消息：

"(#2654) Can't create a duplicate lookalike: You've already created a Lookalike Audience with the same source, country and size. Please try using a different source or different specifications."

在这种情况下，国家和种子是相同的，但两个观众的比例不同。当我在浏览器中通过adsmanager创建完全相同规格的外观时，它们被成功创建

以下是我发送的有效载荷示例：

//Audience successfully created
{
  name: "LLA0%-FB | Engaged | 30 (2020-09-23) (US)",
  subtype: "LOOKALIKE",
  origin_audience_id: "123456789",
  lookalike_spec: {
    type: "reach",
    ratio: 0.05,
    allow_international_seeds: "on",
    location_spec: {
      geo_locations: { countries: ["US"] },
    },
  },
}
//Error
{
  name: "LLA20%-FB | Engaged | 30 (2020-09-23) (US)",
  subtype: "LOOKALIKE",
  origin_audience_id: "123456789", 
  lookalike_spec: {
    type: "reach",
    ratio: 0.2,
    allow_international_seeds: "on",
    location_spec: {
      geo_locations: { countries: ["US"] },
    },
  },
};

api请求的问题在于，您在api请求中同时指定了类型和比率。因此，facebook请求忽略了比率值。 请参阅类型使用类型或比率。你应该像这样使用比率

{
 name: "LLA0%-FB | Engaged | 30 (2020-09-23) (US)",
 subtype: "LOOKALIKE",
 origin_audience_id: "123456789",
 lookalike_spec: {
  type: "reach",
  ratio: 0.05,
  allow_international_seeds: "on",
  location_spec: {
  geo_locations: { countries: ["US"] },
  },
},
}
