Can't start brand new rails app on Heroku

Trying to start up a brand new rails project with heroku, followed the steps in https://devcenter.heroku.com/articles/getting-started-with-rails5 and https://devcenter.heroku.com/articles/getting-started-with-rails6. Both times when I try to push to heroku master, I get

remote: -----> Detecting rake tasks
remote: 
remote:  !
remote:  !     Could not detect rake tasks
remote:  !     ensure you can run `$ bundle exec rake -P` against your app
remote:  !     and using the production group of your Gemfile.
remote:  !     /tmp/build_4403463c/config/boot.rb:5:in `require': cannot load such file -- bootsnap/setup (LoadError)
remote:  !     from /tmp/build_4403463c/config/boot.rb:5:in `<top (required)>'
remote:  !     from /tmp/build_4403463c/bin/rake:7:in `require_relative'
remote:  !     from /tmp/build_4403463c/bin/rake:7:in `<main>'
remote:  !

I've tried to surround the bootsnap/setup with a rescue, and it still hits this block.

In my case, I have 3 bundler versions installed:

gem list bundler

*** LOCAL GEMS ***

bundler (2.2.5, default: 2.1.4, 1.17.3)

Though 2.1.4 being the default, it seems it is not what being used when I bundle install.

I run bundle _2.1.4_ install and then it updates my Gemfile.lock.

# git diff
BUNDLED WITH
-   2.2.5
+   2.1.4

Then the problem was gone when I git push heroku main. I found these links helpful in troubleshooting my issue: Heroku Rails build failing due to Bootsnap and Rake issues and How to switch bundler version?.

Found a solution, In Gemfile.lock I switched RUBY VERSION to ruby 2.6.6p146 and BUNDLED WITH to 1.17.3
