You need to try bundling in this repo as well. I don't expect it to fail because there are very few dependencies here.

But you'll have to navigate back to this project, run bundle install, and then add, commit, and push those changes.

Let me know if there are any problems with that.

@JoshDevHub I did mention that it ran without a problem a few days. So its fine, no error was returned

Ah I see this Gemfile doesn't specify ruby version stuff. That should be okay then. I'll go ahead and merge it.
