我正在使用Apollo Client创建一个应用程序来使用Graphql查询我的服务器.我有一个python服务器,我在其上执行我的graphql查询,从数据库中获取数据,然后将其返回给客户端.

我为客户端创建了一个自定义NetworkInterface,帮助我制作定制服务器请求(默认情况下,ApolloClient对我们指定的URL进行POST调用).网络接口只需要有一个query()方法,其中我们返回表单结果的promise Promise<ExecutionResult>.

我能够进行服务器调用并获取所请求的数据但仍然收到以下错误.

Error: Network error: Error writing result to store for query 
{
   query something{
      row{
         data
      }
   }
}
Cannot read property 'row' of undefined
