server requesting pem passphrase safari push notificiations

I am trying to use the safari-push-notifications npm (https://www.npmjs.com/package/safari-push-notifications) to generate the push package for safari push notifications.

I followed these instructions to prepare my cert.pem and key.pem https://github.com/node-apn/node-apn/wiki/Preparing-Certificates.

When I trigger the route that is trying download my push package, I am prompted for the PEM passphrase. I tried stripping the passphrase from the key.pem with openssl rsa -in key.pem -out key2.pem, but I am still being prompted by the server when that route is hit.

Here is the post route that I have been referring to:

// SAFARI
app.post('/v1/pushPackages/:websitePushID', function(req, res) {

  console.log("route was hit");

  pushLib.generatePackage(
    websiteJson, // The object from before / your own website.json object 
    path.join('assets', 'safari_assets'), // Folder containing the iconset 
    cert, // Certificate 
    key, // Private Key 
    intermediate // Intermediate certificate 
  )
  .pipe(fs.createWriteStream('pushPackage.zip'))
  .on('finish', function () {
      console.log('pushPackage.zip is ready.');
      res.sendFile('pushPackage.zip');
  });
})

Here is the output:

route was hit
Enter PEM pass phrase:

How do I stop this?
