Error-while running node application in APIGEE edg. "Script node executed prematurely

Google Cloud Apigee

Hi,

I am running my node app on APIGEE edge. Code is basicaaly fetching the contents from file in S3 bucket and converting the data to JSON format.

Code snippet:

index.js

var aws = require('aws-sdk');
var csv = require('csvtojson');
var http = require('http');
var apigee = require('apigee-access');

 //aws.config.loadFromPath('./config.json');
 aws.config.update({
    accessKeyId: "key1",
    secretAccessKey: "key2",
    region: "us-east-1"  
});

var s3 = new aws.S3({ apiVersion: '2006-03-01' });
    // Get the object from the event and show its content type
    var bucket = "topup-file-reader";
    console.log("bucket = "+bucket);
    var key = "file.csv";
    console.log("key = "+key);
    var jsonOutput;
    var params = {
        Bucket: bucket,
        Key: key,
    };
    s3.getObject(params, (err, data) => {
        if (err) {
            console.log(err);
            var message = `Error getting object ${key} from bucket ${bucket}. Make sure they exist and your bucket is in the same region as this function.`;
            console.log(message);
           // callback(message);
        } else {
            console.log('CONTENT TYPE:', data.ContentType);
            console.log("data = "+data.Body.toString("utf-8"));
          //  callback(null, data.ContentType);
          //read from file
            var output = data.Body.toString("utf-8");

//converting code to json
                    var Converter = csv.Converter;
                var converter = new Converter({});
                converter.fromString(output,function(err,result){
                        console.log(JSON.stringify(result));
                        jsonOutput = result;
                });
             
        }
    });

http.createServer(function (request, response) {
  apigee.setVariable(request, "jsonOutput", jsonOutput);
  response.writeHead(200, {'Content-Type': 'application/JSON'});
  //response.end('Hello World\n');
}).listen(8124);

console.log('Server running at http://127.0.0.1:8124/');

package.json

{
  "name": "csvreader",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "apigee-access": "^1.3.0",
    "aws-sdk": "^2.9.0",
    "csvtojson": "^1.1.3",
    "http": "0.0.0"
  }
}

I have added dependencies in my apigee edge using node management module. Dependencies are added with zip modules.

Code is working fine on my local machine but getting error on apigee

{
  "fault": {
    "faultstring": "Script node executed prematurely: syntax error\nsyntax error\n    at module.js:439\n    at module.js:474\n    at module.js:356\n    at module.js:312\n    at module.js:497\n    at startup (trireme.js:142)\n    at trireme.js:923\n",
    "detail": {
      "errorcode": "scripts.node.runtime.ScriptExitedError"
    }
  }
}

Please help in identifying the error

Hi @ajain84 ,

I think issue is with

s3.getObject(params, (err, data) => {
	// Your code here
});

Replace it with following and try.

s3.getObject(params, function (err, data) {
	// Your code here
});
