erro do vagrant com aws

meu arquivo Vagrantfile tá assim:

Vagrant.configure("2") do |config|

  config.vm.box = "ubuntu_aws"
  config.vm.box_url = "https://github.com/mitchellh/vagrant-aws/raw/master/dummy.box"

  config.vm.provider :aws do |aws, override|
    aws.access_key_id = "XXXXXXXXXX"
    aws.secret_access_key = "XXXXXXXXXXXXXXX"

    aws.keypair_name = "devops"
    aws.ami = "ami-efd0428f"
    aws.security_groups = ['devops']
    aws.instance_type = "t2.micro"

    override.ssh.username = "ubuntu"
    override.ssh.private_key_path = "devops.pem"
  end

  config.vm.define :web do |web_config|
    web_config.vm.provider :aws do |aws|
      aws.tags = { 'Name' => 'MusicJungle (vagrant)'}
    end
  end

end

e quando eu dou um 'vagrant up --provider=aws', dá a seguinte mensagem:

There was an error talking to AWS. The error message is shown
below:

InvalidParameterValue => Value () for parameter groupId is invalid. The value cannot be empty

se alguém puder me ajudar, vou agradecer bastante
