node.js – Nodejs – 从另一个lambda函数中调用AWS.Lambda函数

但是,当我尝试在Lambda函数中使用它时,我收到以下错误：

AWS lambda undefined 0.27s 3 retries] invoke({ FunctionName: 'my-function-name',InvocationType: 'requestResponse',LogType: 'Tail',Payload: <Buffer > })

如何在Lambda函数中调用Lambda函数？

我的功能：

'use Strict';

var AWS = require("aws-sdk");

var lambda = new AWs.Lambda({
    apiVersion: '2015-03-31',endpoint: 'https://lambda.' + process.env.DYNAMODB_REGION + '.amazonaws.com',logger: console
});

var lambdaHandler = {};

// @var payload - type:string
// @var functionName - type:string
lambdaHandler.invokeFunction = function (payload,functionName,callBACk) {

    var params = {
        FunctionName: functionName,/* required */
        InvocationType: "requestResponse",LogType: "Tail",Payload: new Buffer(payload,'utf8')
    };

    var lambdarequestObj = lambda.invoke(params);

    lambdarequestObj.on('success',function(responsE) {
        console.log(response.data);
    });

    lambdarequestObj.on('error',function(responsE) {
        console.log(response.error.messagE);
    });

    lambdarequestObj.on('complete',function(responsE) {
        console.log('Complete');
    });

    lambdarequestObj.send();

    callBACk();
};

module.exports = lambdaHandler;
