Cannot deploy to Heroku

I keep getting the error: “SyntaxError: Unexpected token >”, even when using the default meteor files (by running meteor create and not modifying any files).

The default app runs fine on my localhost:3000. I also get this error on a larger website I’m working on (which also works well locally, and I was able to successfully deploy once but have been unsuccessful afterwards) and am surprised I’m getting the error with the default files

What buildpack are you using?

I got it working with this buildpack:
https://github.com/AdmitHub/meteor-buildpack-horse.git

Here are some instructions on how to do it:

The one thing those instructions seem to be missing is the MongoDB. Add Mongo using the following command:

heroku addons:create mongolab

Not an expert but this setup worked for me.
