@picandocodigo can you please review this PR?

Hi @sonianand11,
Thanks for submitting this PR. GitHub has some features in place to redirect to main when there's a request to master and it seems to be working as expected with bundler for me. What error were you getting when running bundle install and what versions of Bundler and Ruby were you using?

@picandocodigo Thank you for quick response.
Current ruby version is ruby 2.7.2p137 (2020年10月01日 revision 5445e04352) [x86_64-linux]
I am using bundler version 2.1.4 and here is the error

Fetching https://github.com/elastic/elasticsearch-rails.git
fatal: Needed a single revision
Git error: command `git rev-parse --verify master` in directory

I am executing bundle install inside examples directory i.e. elasticsearch-rails/elasticsearch-persistence/examples/notes

If I do git branch in elasticsearch-rails/elasticsearch-persistence/examples/notes it is showing main branch instead of master since we already have changed that.

Hi @sonianand11. If you update Bundler to a version >= 2.2.5, it will just work and there's no need to change the Gemfile.
