Dokku fails due to bundler version

I had a Ruby on Rails app up and running with Dokku. When I tried to deploy it again today, I received the following error:

--> Installing dependencies using bundler 2.0.1
       Running: bundle install --without development:test --path vendor/bundle --binstubs vendor/bundle/bin -j4 --deployment
       Activating bundler (2.0.2) failed:
       Could not find 'bundler' (2.0.2) required by your /tmp/build/Gemfile.lock.
       To update to the latest version installed on your system, run `bundle update --bundler`.
       To install the missing version, run `gem install bundler:2.0.2`
       Checked in 'GEM_PATH=vendor/bundle/ruby/2.5.0', execute `gem env` for more information

       To install the version of bundler this project requires, run `gem install bundler -v '2.0.2'`
       Bundler Output: Activating bundler (2.0.2) failed:

       !
       !     Failed to install gems via Bundler.

Not sure how to resolve this and was unable to find any references to this type of problem with Dokku.

The update didn't change the Bundler version for me.

I solved this by changing the buildpack. Syntax for dokku is:

$ dokku config:set --no-restart YOUR_APP BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-ruby.git#v227

#227 gives Bundler 2.2.16 which works with my installed version 2.2.20.

Here is a list of available buildpacks.

I solved this by updating Dokku using their official documentation. After the update, I had no trouble deploying.
