Ruby - no implicit conversion of Symbol into Integer

I'm trying to create AWS Security Group but I'm getting the error no implicit conversion of Symbol into Integer during ec2.create_security_group(GroupName=sg_name, VpcId=vpc_id)

I'm following this documentation. Any idea how to resolve the error?

begin
 
  ec2 = get_aws_client
  prov = $evm.root['miq_provision_request'] || \
      $evm.root['miq_provision'] || \
      $evm.root['miq_provision_request_template']
  vpc_id = prov.get_option(:dialog_cloud_network).to_s.strip 
  #prov.get_option(:dialog_vm_name).to_s.strip 
  sg_name = 'test_sg_manageiq'
  
  #ec2.create_security_group({vpcid: vpc_id, groupname: sg_name})

  ec2.create_security_group(GroupName=sg_name, VpcId=vpc_id)

rescue => err
  log(:error, "[#{err}]\n#{err.backtrace.join("\n")}")
  exit MIQ_ABORT
end

Error:

An "no implicit conversion of Symbol into Integer" error almost always means that you have an array or string where you're expecting to have a hash. In your case, the suspicious code is:

#ec2.create_security_group({vpcid: vpc_id, groupname: sg_name})
ec2.create_security_group(GroupName=sg_name, VpcId=vpc_id)

The create_security_group call you're using looks more like Python than Ruby to me and is equivalent to:

GroupName = sg_name
VpcId = vpc_id
ec2.create_security_group(GroupName, VpcId)

so you're passing a string (sg_name) to a method that expects a hash of parameters:

#create_security_group(params = {}) ⇒ Types::CreateSecurityGroupResult

Creates a security group.
[...]

Then create_security_group tries to treat sg_name as the params hash it is expecting and that triggers the exception.

I think you want to use the code you commented out and fix the keys to include underscores as per the documentation:

ec2.create_security_group(vpc_id: vpc_id, group_name: sg_name)
