Bundler in heroku looking for concurrent-ruby-1.1.0 - ruby-on-rails

Question

I'm having trouble trying to push to heroku a fresh new rails app: git push heroku master
remote: Fetching gem metadata from https://rubygems.org/.........
remote: Fetching version metadata from https://rubygems.org/..
remote: Fetching dependency metadata from https://rubygems.org/.
remote: Could not find concurrent-ruby-1.1.0 in any of the sources
remote:
remote: !
remote: ! Failed to install gems via Bundler.
remote: !
It's true, concurrent-ruby-1.1.0 doesn't exist, version 1.0.5 does. concurrent-ruby-1.0.5
When i looked to my local Gemfile.lock , i can see a line concurrent-ruby (1.1.0)
I tried to uninstall Bundler, reinstall Bundler, remove Gemfile.lock. In my Gemfile file there is nothing related to concurrent-ruby.
I show you my Gemfile.lock , you can double check that there is several concurrent-ruby dependencies but just only one is -v 1.1.0 (witch doesn't exist on rubygems.org

Am I the only one with this issue ? Thank you for you help
EDIT: SOLUTION
To resolve this issue, add to your Gemfile this line:
gem 'concurrent-ruby', '~> 1.0.5'
Then run bundle update concurrent-ruby , git add, git push then you are ready to deploy to Heroku.

Answer 1

I had the same issue and to fix it I run a bundle update that updated on my local app to the version concurrent-ruby (1.1.2).
I tested in local and after commit on git, deploy it with git push heroku master:master and it works now.
I post below the Gemfile.lock and the log of the deploy.
Good luck,
Marc
