意外的输入结束：从API API网关获取响应时发生ApolloClient错误

我在我的Angualar应用程序中使用Apollo，现在正在处理此问题。我在AWS Lambda上有一个GraphQL端点，并且通过API网关，我看到响应正确回来，但是当它读完它时，它会引发此错误。 AWS使用LAMBDA_PROXY意外的输入结束：从API API网关获取响应时发生ApolloClient错误

//setup 
const client = new ApolloClient({ 
    networkInterface: createNetworkInterface({ 
    opts: { 
     mode: 'no-cors', 
    }, 
    uri: "https://xxxxxxx.execute-api.ap-southeast-2.amazonaws.com/dev/graphql" 
    }), 
}); 

//make the call 
this.apollo.watchQuery({ 
     forceFetch: true, 
     query: QueryToSend 
    }).subscribe(({data}) => { 
     ...process... 

    }, error => { 
     console.log(error); 
    }); 

//the error... 
Network error: Unexpected end of input 
    at new ApolloError (ApolloError.js:31) 
    at QueryManager.js:128 
    at t.invoke (polyfills.js:3) 
    at Object.onInvoke (ng_zone.js:236) 
    at t.invoke (polyfills.js:3) 
    at e.run (polyfills.js:3) 
    at polyfills.js:3 
    at t.invokeTask (polyfills.js:3) 
    at Object.onInvokeTask (ng_zone.js:227) 
    at t.invokeTask (polyfills.js:3)

请求是

const QueryToSend= gql` 
    query data { 
     getSuperDefinitionList{ 
      id, 
      name, 
     } 
    } 
`;

不知道什么是错的。我从Postman和SoapUI调用相同的请求体。我甚至看到提琴手响应具有正确的响应...

HTTP/1.1 200 OK 
Content-Type: application/json 
Content-Length: ... 
Connection: keep-alive

{"data":{"getSuperDefinitionList":[{"id":"83d3b09f-a947-4a33-bcb0-f5c9e0446ace","name":"S","__typename":"SuperDefinitionType"}]}}

所有看起来不错，从AWS但阿波罗或一些JavaScript库，它使用没有。

我该怎么办？

写完后我有一个预感。

我删除

opts: { 
    mode: 'no-cors', 
},

，并确保我回到正确的头（最后3省略）：

 var response = new APIGatewayProxyResponse 
     { 
      StatusCode = result.Result.IsError ? (int)HttpStatusCode.BadRequest : (int)HttpStatusCode.OK, 
      Body = result.Result.Body, 
      Headers = new Dictionary<string, string> { 
       { "Content-Type", "application/json" }, 
       { "Access-Control-Allow-Origin", "*" }, 
       { "Access-Control-Allow-Methods", "GET,POST,OPTIONS" }, 
       { "Access-Control-Allow-Headers", "Connection, Host, Origin, Referer, Access-Control-Request-Method, Access-Control-Request-Headers, User-Agent, Accept, Content-Type, Authorization, Content-Length, X-Requested-With, Accept-Encoding, Accept-Language" }, 
      } 
     };
