        stack,
        'HelloMachine',
        'arn:aws:states:ap-northeast-1:1233445556:stateMachine:Helloworld',
    );

    const stepFunctionsDatasource = graphApi.addHttpDataSource(
        'StepFunctions',
        'https://states.ap-northeast-1.amazonaws.com',
        {
            name: 'StepFunctionsDataSource',
            authorizationConfig: {
                signingRegion: 'ap-northeast-1',
                signingServiceName: 'states',
            },
