I am trying to create a security group with CIDR another security group using its ID but I am getting the following error has a problem: "sg-12345678" is not a valid CIDR block: invalid CIDR address: sg-12345678. Examine values at 'SecurityGroup.Ingresses'. My code:

lb_sg = aws.ec2.get_security_group(                        
    tags={"Name": "my-lb"}"
)                                                          

sg = aws.ec2.SecurityGroup(                                  
    "web-lb",                                            
    vpc_id=vpc_id,                                           
    description="Enable HTTP access from Load Balancer",     
    ingress=[                                                
        aws.ec2.SecurityGroupIngressArgs(                    
            protocol="tcp",                                  
            from_port=args.port,                             
            to_port=args.port,                               
            cidr_blocks=[lb_sg.id)],                     
        )                                                    
    ],                                                       
    egress=[                                                 
        aws.ec2.SecurityGroupEgressArgs(                     
            protocol="-1",                                   
            from_port=0,                                     
            to_port=0,                                       
            cidr_blocks=["0.0.0.0/0"],                       
        )                                                    
    ],                                                       
)

I think the error is kinda self-explanatory. You have to pass CIDR there, not a string name (like

sg-12345678

).

Thank you!
