AWS cloud runner not deploying when I specify a security group

I’m launching a runner with the command in Github Actions.

cml-runner \
          --cloud aws \
          --cloud-region eu-west-1 \
          --cloud-type=g4dn.2xlarge \
          --cloud-aws-security-group="123123123123" \
          --labels=cml-runner

Without specifying security group it works, I presume by launching in the default group. However, when I run the above I get a terraform error,

Error: Failed creating the machine: no Security Groups found\n│ \n│   with iterative_cml_runner.runner,\n│   on main.tf line 14, in resource \"iterative_cml_runner\" \"runner\":\n│   14: resource \"iterative_cml_runner\" \"runner\" {\n│ \n╵\n","stack":"Error: terraform -chdir='/home/runner/.cml/cml-4vgypkb6gn' apply -auto-approve\n\t\nTerraform used the selected providers to generate the following execution\nplan. Resource actions are indicated with the following symbols:\n  + create\n\nTerraform will perform the following actions:\n\n 

How do I debug this?

@skailasa it might be unclear in the docs, this param takes the security group name and not the ID, see this:

Thank you all for the help here, this is working using the security group name 🚀
