Hi, does anyone know how I can get past a 'duplicate security group' error. The issue seems to have been fixed in Terraform about 6 years ago!

```  aws:ec2:SecurityGroupRule (wiki-https-external-0-egress):
    error: 1 error occurred:
    	* [WARN] A duplicate Security Group rule was found on (sg-002096ed4ca1220a3). This may be
    a side effect of a now-fixed Terraform issue causing two security groups with
    identical attributes but different source_security_group_ids to overwrite each
    other in the state. See <https://github.com/hashicorp/terraform/pull/2376> for more
    information and instructions for recovery. Error: InvalidPermission.Duplicate: the specified rule "peer: 0.0.0.0/0, TCP, from port: 443, to port: 443, ALLOW" already exists
    	status code: 400, request id: 1b6001e7-2dc7-437f-aa56-c92a32fa707b```

Here's my about:

<@U03PZ9BDS9M> did you try to use the AWS Native provider that doesn’t depend on Terraform? <https://www.pulumi.com/registry/packages/aws-native/> -&gt; EC2 - <https://github.com/pulumi/pulumi-aws-native/blob/master/sdk/nodejs/ec2/getSecurityGroup.ts|getSecurityGroup.ts>

Thanks for the reply <@U01FHMA71BK>, not yet, I'm just getting started with Pulumi :slightly_smiling_face:

I've commented out the following part of my load balancer setup and it seems to have fixed things:

```const alb = new awsx.elasticloadbalancingv2.ApplicationLoadBalancer(
  'wiki-loadbalancer',
  { external: true, /*securityGroups: cluster.securityGroups,*/ vpc }
)```

<@U03PZ9BDS9M> can you share your code? this is usually because the security group is going to the wrong vpc

That might have been it. The above change (commenting out the above) fixed everything, so I now have a nice fargate running stack :+1:
