Web サーバーで apollo-client を使用して、graphql サーバー (また apollo) と通信しています。クエリが正常に動作し、データを適切に取得していますが、ミューテーションを試みると、new ApolloErrorメッセージが表示されます。Graphiqlにコピー/貼り付けされた同じ突然変異は完全に機能します。
Graphql サーバーで CORS を確認しましたが、有効になっており、正しく機能しています。ミューテーションをコードから文字通りコピーして、graphiql エディターに貼り付けましたが、期待どおりに動作します。
誰かが私のためにこれに光を当てることができますか、またはエラーが発生する理由について私のgraphql-serverに関する詳細情報を確認する方法を教えてもらえ400ますか?
これがアポロエラーです

**** 更新 **** apolloMiddlewarereq.headers と req.body を console.log する前に、ミドルウェアを追加しました
req.headers -------
{
"accept": "*/*",
"content-type": "application/json",
"authorization": "JWT ",
"accept-encoding": "gzip,deflate",
"user-agent": "node-fetch/1.0 (+https://github.com/bitinn/node-fetch)",
"connection": "close",
"content-length": "585",
"host": "localhost:9000"
}
req.body -------
{
"query": "mutation updateTwitterAccessToken($data: TokenInput!) {\n updateTwitterToken(data: $data) {\n _id\n services {\n twitter {\n id\n __typename\n }\n token {\n token\n expires\n __typename\n }\n __typename\n }\n __typename\n }\n}\n",
"variables": {
"data": {
"accessToken": "000700000-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"accessTokenSecret": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"_id": "yyyyyyyyyyyyyyyyy",
"service": "twitter",
"serviceId": "000700000"
}
},
"operationName": "updateTwitterAccessToken"
}
私はclient.mutate({ ... })自分の Web サーバーから呼び出していますが、req.bodyここでは次のように設定しています。
req.body -------
{
"query": "mutation ..."
....
}
なぜそうでは"query": "mutation ..."ないの"mutation": "mutation ..."ですか？
