google-auto-auth error

[santhoshdc1590]

Anyone help on fixing this google auth error that is being generated, while using the emulator?

This is my index.js file after the build

var googleAuth = require('google-auto-auth')();
//Handle Background events according to spec
function shimHandler(data) {
  return new Promise((resolve, reject) => {
    googleAuth.getToken(function (err, oauthToken) {
      if (err) { console.log('googleAuth error')
        reject()
      } else {
        const p = require('child_process').execFile('./dist/{{config["output_name"]}}/{{config["output_name"]}}', {
          env: Object.assign(process.env, {
            'GOOGLE_OAUTH_TOKEN': oauthToken,
          })
        });
        var lastMessage;
        p.stdin.setEncoding('utf-8');
        //Log standard err messages to standard err
        p.stderr.on('data', (err) => {
          console.error(err.toString());
        })
        p.stdout.on('data', (out) => {
          console.log(out.toString());
          lastMessage = out;
        })
        p.on('close', (code) => {
          if (code !== 0) {
            //This means the shim failed / panicked. So we reject hard.
            reject();
          } else {
            // Resolve the promise with the latest output from stdout
            // In case of shimming http, this is the response object.
            resolve(lastMessage);
          }
        });
        //Write the object/message/request to the shim's stdin and signal
        //End of input.
        p.stdin.write(JSON.stringify(data));
        p.stdin.end();
      }
    });
  });
}

//Handle http request
function handleHttp(req, res) {
  var requestBody;
  console.log(req.get('content-type'))
  switch (req.get('content-type')) {
    case 'application/json':
      requestBody = JSON.stringify(req.body);
      break;
    case 'application/x-www-form-urlencoded': //application/x-www-form-urlencoded
      //The body parser for cloud functions does this, so just play along
      //with it, sorry man! Maybe we should construct some kind of proper
      //form request body? or not. let's keep it this way for now, as
      //This is how cloud functions behaves.
      //req.setHeader('content-type', 'application/json')
      requestBody = JSON.stringify(req.body);
      break;
    case 'application/octet-stream':
      requestBody = req.body;
      break;
    case 'text/plain':
      requestBody = req.body;
      break;
  }

  var fullUrl = req.protocol + '://' + req.get('host') + req.originalUrl;
  console.log('Request body ');console.log(JSON.stringify(requestBody));
  console.log('Request headers');console.log(JSON.stringify(req.headers));
  console.log('Request method'); console.log(JSON.stringify(req.method));
  console.log('Request remote_addr'); console.log(JSON.stringify(req.ip));
  console.log('Req protocol'); console.log(JSON.stringify(req.protocol));
  console.log('Req get host'); console.log(JSON.stringify(req.get('host')));
  console.log('originalUrl'); console.log(JSON.stringify(req.originalUrl));

  var httpRequest = {
    'body': requestBody,
    'headers': req.headers,
    'method': req.method,
    'remote_addr': req.ip,
    'url': fullUrl
  };

  shimHandler(httpRequest)
  .then((result) => {
    console.log('should come here')
    data = JSON.parse(result);
    res.status(data.status_code);
    res.set(data.headers)
    res.send(data.body);
  })
  .catch((e) => {
    console.log(e);
    console.log('some error has occurred');
    res.status(500).end();
  })
}

//{% if config["trigger_http"] %}
exports['{{config["function_name"]}}'] = function(req, res) {
  return handleHttp(req, res);
}//{% else %}
exports['{{config["function_name"]}}'] = function(event, callback) {
  return shimHandler(event.data).then(function() {
    callback();
  }).catch(function() {
    callback(new Error("Function failed"));
  });
}//{% endif %}

This is what I get on running logs using

functions logs read

My pip crashes if I install pip install google-cloud-core, I'm using python3.5

Have I missed any of the required library?

I did solve this google-auth error once I ran this gcloud auth application-default login command Credit , Documentation

@MartinSahlen I'm a beginner in this google cloud itself. May be you can add this to your procedure of how to get google auth permission for beginner how would want to use this.
