Getting error: not supported when using pubsub.publish or pubsub.create topic.

Environment details

• OS: macOS
• Node.js version: v10.15.3
• npm version: 6.4.1
• @google-cloud/pubsub version: “^0.28.1”

Steps to reproduce

1. Used the following code to publish to an existing topic with a key that works with pubsub in another app I used:

try {
    data = 'my_Data'
    const pubsub = new PubSub({
      projectId: config.gcloudProjectID,
      keyFilename: './pubSubKey.json',
    });
    const payload = JSON.stringify({ someData: data });
    const dataBuffer = Buffer.from(payload);
    const messageId = await pubsub.topic(config.topicName).publish(dataBuffer);
  } catch (err) {
    logError('Failed to publish pubsub with error: ', err);
    throw err;
  }

I used a similar setup as above in another project and it worked fine.

1. I then get the following error:

@callmehiphop We were able to resolve this issue. Since we did server side rendering we had some of our node intertwined with libraries that set the “window” variable and stored data in it. By the time we required the google-cloud pubsub library, the window was set and util.isNode resolves to false. We moved the require that included our pubsub code to run before any libraries that set the window object, and this resolved the issue for us a s util.isNode is true by the time it runs.

@hbk899 @danieldanielecki you can fix by adding process to your fake window in the server.ts file

win.process = process;
