I can't seem to configure my rails app properly. I had a perfectly working rails app deployed on Heroku. I added the datadog buildpack and then started getting the following build error:

remote:  !     You must use Bundler 2 or greater with this lockfile.

After removing my Gemfile.lock and reinstalling and making sure bunder version was > 2.0, I then started getting another build error. This time it was that the bundler version my project needs is < 2: 

remote:        Bundler Output: Activating bundler (< 2) failed:
remote:        Could not find 'bundler' (1.17.3) required by your /tmp/build_3b256cc6024c5dcfd1bd0d030688678a/Gemfile.lock.
remote:        To update to the lastest version installed on your system, run `bundle update --bundler`.
remote:        To install the missing version, run `gem install bundler:1.17.3`
remote:        Checked in 'GEM_PATH=vendor/bundle/ruby/2.5.0', execute `gem env` for more information
remote:        
remote:        To install the version of bundler this project requires, run `gem install bundler -v '< 2'`
remote:

remote:  !

remote:

remote: Verifying deploy...

I'm not sure how to move forward debugging this error. I don't know how to access the /tmp/build folder and I'm not sure what I would do if I did.

Please any direction or suggestions would be greatly appreciated.

I've already tried pushing to heroku master with various versions of bundler. There is always a problem with the build. I feel like there are multiple areas where bundler is required in the build and in the actual project, and that they require different versions, but I don't know how to find them.

Here is my Gemfile:

RUBY VERSION
   ruby 2.5.1p57

BUNDLED WITH
   2.0.1

I'd like to be able to find where the areas are in my code that are requiring different versions of bundler. Or be able to circumvent the issue with a different gem. If anyone can help me get the Heroku build to work I would be very grateful.
