我以前没有遇到过这种情况，但只需 1 个突变就会创建 2 个条目：

突变前的数据：

{
  "data": {
    "allAdminConfigCategories": {
      "edges": []
    }
  }
}

突变：

  mutation something($name: String!) {
    createAdminConfigCategory(input: { adminConfigCategory: { name: $name } }) {
      query {
        allAdminConfigCategories {
          edges {
            node {
              id
            }
          }
        }
      }
    }
  }

变量

{ "name": "Jamie" }

突变后的数据：

{
  "data": {
    "createAdminConfigCategory": {
      "query": {
        "allAdminConfigCategories": {
          "edges": [
            {
              "node": {
                "id": 42
              }
            },
            {
              "node": {
                "id": 43
              }
            }
          ]
        }
      }
    }
  }
}

我在 graphiql 中执行这些查询：

您没有在这里创建两个条目；你的突变：

mutation something($name: String!) {
  createAdminConfigCategory(input: { adminConfigCategory: { name: $name } }) {
    query { # < Here's the issue
      allAdminConfigCategories {
        edges {
          node {
            id
          }
        }
      }
    }
  }
}

正在请求query突变有效负载上的字段，这使您可以再次访问整个 GraphQL 模式。然后，您可以使用它来查询allAdminConfigCategories，这将为您提供您可以查看的所有管理配置类别（不仅仅是您刚刚创建的类别）。

您想要的突变可能更像这样：

mutation something($name: String!) {
  createAdminConfigCategory(input: { adminConfigCategory: { name: $name } }) {
    adminConfigCategory {
      id
    }
  }
}

在这里，我们只是直接从突变有效负载中查询新创建的 AdminConfigCategory。
