App Engine doesn't read a file

[Giancarlo C.]

Hi everybody, I'm new in this kind of platform (cloud) and I have a problem with App Engine.

I have the following project structure in App Engine:

- Root

  - nodejs-docs-samples

  - src

    - be-nodejs-piloto

       - node_modules

       - api.js (api post uri)

       - app.js (main)

       - app.yaml

       - datastore-quickstart.json

       - package-lock.json

       - package.json

    - vibrant-tree-191664

app.yaml (content)

runtime: nodejs

env: flex

manual_scaling:

  instances: 1

resources:

  cpu: 1

  memory_gb: 0.5

  disk_size_gb: 10

api.js (content)

'use strict';

// Load libs.

var express  = require('express');

var router   = express.Router();

var path = require('path');

const Datastore = require('@google-cloud/datastore'); // Imports the Google Cloud client lib

// Your Google Cloud Platform project ID

const projectId   = 'datastore-quickstart-191515';

const keyFilename = '/home/testcloud99/src/be-nodejs-piloto/datastore-quickstart-5672f2cde8ca.json';

console.log('keyFilename:' + keyFilename);

// Creates a client

const datastore = new Datastore({

    projectId: projectId,

    keyFilename: keyFilename

  });

router.route('/api/piloto')

    .post(function (req, res)

    {

    console.log('method: POST');

        // Read params

        var pMsgId   = req.body.msgId;

        const query = datastore.createQuery('MyEntity');

        query.filter('msgId', '=', pMsgId);

        // exec query

        datastore

            .runQuery(query)

            .then(results => {

                //OK

                return res.status(200).jsonp({

                    "piloto":

                    {

                        "code" : 0,

                        "desc" : "ok",

                    }

                });

        })

        .catch(err => {

            console.error('ERROR:', err);

            return res.status(200).jsonp({

                "piloto":

                {

                    "code" : 1,

                    "desc" : "error",

                    "errorMessage" : err.message

                }

                });

        });

    });

module.exports = router;

So, when I send a POST message (using soapUI), I get this response:

{"piloto": {

   "code": 1,

   "desc": "error",

   "errorMessage": "ENOENT: no such file or directory, open '/home/megagecs/src/be-nodejs-piloto/datastore-quickstart-5672f2cde8ca.json'"

}}

I guess App Engine isn't recognizing that JSON file but I don't know why. Any kind of configuration that should be done?

Hope you can help me.

Regards.

Hello Giancarlo, 

Did you deploy your app? Do you test it using the local server? 

You seem to try using the local system in the app engine standard environment, which is not possible.
