```ruby
class HealthcheckController < ActionController::Base
  # rescue_from ApiEntity::Error do |e|
  #   render text: '', status: :error
  # end

  def check
    # Check API connectivity
    # Section.all
    render json: { git_sha1: CURRENT_RELEASE_SHA }
  end
end
```

Fix Healthcheck action, check for db connectivity

class HealthcheckController < ActionController::Base
  def check
    User.first # test db connectivity
    render json: { git_sha1: CURRENT_RELEASE_SHA }
