Hi Paul (Bonjour?). Have you tried to call ?

```vpc = aws.ec2.get_vpc(default=True)
print(vpc.arn)
...```

are you suggesting i pass the arn as the id?

so the `vpc = aws.ec2.get_vpc(default=True)` works when `vpc = aws.ec2.DefaultVpc(f'default-vpc')` does not

No using vpc.arn was just a way to show it was actually retrieving the default vpc correctly.

Re: DefaultVpc(), bear in mind this is an "advanced" resource. If you need to manipulate or use your vpc, either create a new (non-default) one, or get the default vpc as I showed above.

The doc says about DefaultVpc() <https://www.pulumi.com/docs/reference/pkg/aws/ec2/defaultvpc/>

```This is an advanced resource, and has special caveats to be aware of when using it. Please read this document in its entirety before using this resource.```

From reading your code above, I would say you should be able to achieve the same with the regular Vpc class.

Running this:

```import pulumi_aws as aws

vpc = aws.ec2.get_vpc(default=True)
subnet_ids = aws.ec2.get_subnet_ids(vpc_id=vpc.id)
print(subnet_ids.ids)```
should output something similar to this:
```['subnet-204bcd78', 'subnet-f66a7d91', 'subnet-22b1b06b']```
