我使用 graphql-tools 缝合了两个 graphql 端点。使用一个端点架构它工作正常，但使用另一个架构它会抛出此错误“GraphQLError：在类型中找不到字段：'query_root'”。即使我可以在内省时看到所有模式。

    const createRemoteExecutableSchemas = async () => {
        let schemas = [];
        for (let api of graphqlApis) {
            const http =  http_link.HttpLink({
                uri: api.uri,
                fetch:fetch
            });
            const link1 = setContext.setContext((request, previousContext) => {
                return {
                    headers:{authorization: previousContext.graphqlContext.headers.authorization}
                }
            }).concat(http);

            const link2 = setContext.setContext((request, previousContext) => ({
                headers: {
                    'x-hasura-admin-secret': api.secret
                }
              })).concat(http);
            const remoteSchema = await gtool.introspectSchema(link2);
            const remoteExecutableSchema =  gtool.makeRemoteExecutableSchema({
                schema: remoteSchema,
                link:link1
            });
            schemas.push(remoteExecutableSchema);
        }
        return schemas;
    };

    const createNewSchema = async () => …
