parse-server: Parse.Query not working on Heroku (No Such App error)

Environment Setup

• Used the ‘deploy to heroku’ button from the migration guide

Steps to reproduce

• Upload this cloudcode function and call it

Parse.Cloud.define('debuggingFn', function(request, response) {
  var query = new Parse.Query("Speech");
  query.equalTo("speechId", "s_1456277936842");
  query.find({
    success: function(results) {
      console.log('SUCCESS', results)
      response.success("Success", results);
    },
    error: function(a, b) {
      // ERROR CAUGHT HERE: 'Heroku | No such app'
      console.log('ERROR', a, b)
      response.error("Error");
    }
  });
});

Logs/Trace

• I expect to get a result, instead I get a (from the parse server logs)

ParseError {
2016-04-24T04:39:20.444057+00:00 app[web.1]:   code: 107,
2016-04-24T04:39:20.444079+00:00 app[web.1]:   message: 'Received an error with invalid JSON from Parse: _<bunch of html>_ <h1><strong>Heroku | No such app</strong></h1>\n            <div class=\'article\'>\n              <p>There is no app configured at that hostname.<br/>Perhaps the app owner has renamed it, or you mistyped the URL. _<bunch of html>_

Queries from the client website to my parse server work fine. Only the cloud code queries fail.

I believe I’ve followed every step from the migration guide, but googling doesn’t return anyone else having this issue. So I guess I missed something?

This is the dependencies from my package.json file in the parse server project:

  "dependencies": {
    "express": "~4.11.x",
    "kerberos": "~0.0.x",
    "parse": "~1.8.0",
    "parse-server": "~2.2.7",
    "cors": "*"
  },
