/grape-reload-ad29dd32ab27/lib/grape/reload/dependency_map.rb:96:in `[]': no implicit conversion of Symbol into Integer (TypeError)

Got above error whilst starting rack app and a file containing

  def dummy_devices_learn
    hash_to_be_inserted = {:actions => ["learn"]}

    dummy_devices.map { |key, value|
      [key, value.merge hash_to_be_inserted]
    }.to_h

  end

this seems to resolve the issue

  def dummy_devices_learn
    hash_to_be_inserted = {:actions => ["learn"]}

    dummy_devices.map { |key, value|
      [key, value.merge(hash_to_be_inserted)]
    }.to_h

  end

Be aware of the brackets around hash_to_be_inserted
