Dependabot can't resolve your Ruby dependency files

[dependabot-preview]

Dependabot can't resolve your Ruby dependency files.

As a result, Dependabot couldn't update your dependencies.

The error Dependabot encountered was:

Bundler::VersionConflict with message: Bundler could not find compatible versions for gem "bundler":
  In Gemfile:
    guard-bundler was resolved to 3.0.0, which depends on
      bundler (>= 2.1, < 3)

  Current Bundler version:
    bundler (1.17.3)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?

Could not find gem 'bundler (>= 2.1, < 3)', which is required by gem 'guard-bundler', in any of the sources.

If you think the above is an error on Dependabot's side please don't hesitate to get in touch - we'll do whatever we can to fix it.
