Project ID not automatically determined from key file

Pub/Sub authentication documentation suggests that the project ID will be determined automatically if you provide a keyFilename or GOOGLE_APPLICATION_CREDENTIALS

If you wish, you can set an environment variable (GCLOUD_PROJECT) in place of specifying this inline. Or, if you have provided a service account JSON key file as the config.keyFilename property explained above, your project ID will be detected automatically.

Source: https://googlecloudplatform.github.io/google-cloud-node/#/docs/pubsub/0.15.0/guides/authentication

I can’t get the “your project ID will be detected automatically” bit to work, and still need to provide projectId expressly (either as GCLOUD_PROJECT env variable or to the configuration call). This feature isn’t really mentioned anywhere else, so maybe it’s unsupported? Seems like a good idea though!

This may be related to this issue: https://github.com/GoogleCloudPlatform/google-cloud-node/issues/2576

Environment details

• OS: macOS 10.13.2
• Node.js version: 8.9.1
• npm version: 5.6.0
• @google-cloud/pubsub version: 0.16.0

Steps to reproduce

1. Let pubsub be configured using only keyFilename or GOOGLE_APPLICATION_CREDENTIALS
2. Try to subscribe to some topic

Sample code:

const pubsub = require('@google-cloud/pubsub')();

const subscription = pubsub.subscription('test-subscription');
subscription.on('message', message => {
  console.log('message received');
  message.ack();
});

Error message:

events.js:183
      throw er; // Unhandled 'error' event
      ^

Error: Requested project not found or user does not have access to it (project={{projectId}}). Make sure to specify the unique project identifier and not the Google Cloud Console display name.

I believe I found a fix: #74

@victorandree would you mind trying again?

$ npm install --save git+https://github.com/stephenplusplus/nodejs-pubsub.git#spp--23

double checks for nodejs-storage instead of nodejs-pubsub… nope, we’re good 😃

[victorandree]

@stephenplusplus Yes, it works! And I verified again that it does not work without this patch so I think you fixed it 😃
