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 "sinatra":
  In snapshot (Gemfile.lock):
    sinatra (= 1.4.8)

  In Gemfile:
    sinatra

    sinatra-contrib (>= 1.4.7, <= 2.0.5) was resolved to 2.0.0, which depends on
      sinatra (= 2.0.0)

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.

Bundler could not find compatible versions for gem "weak_observable":
  In Gemfile:
    hallon was resolved to 0.18.2, which depends on
      weak_observable (~> 1.0)

Could not find gem 'weak_observable (~> 1.0)', which is required by gem 'hallon', 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.
