`ec2 Vpc getSubnets` returns a `Promise lt ec2 Subnet gt ` as opposed to an `Output lt ec2 Subnet gt ` Is this safe to use as an arg Input to a subsequent resource where I need to provide a subnet id

What < magnificent lifeguard 15082> suggested worked as a charm heart ```const publicSubnetsIds = vpc id apply async = gt vpc getSubnetsIds public ``` and then I use it like this ```const alb = new aws lb LoadBalancer `$ name alb` internal false loadBalancerType application securityGroups albSecGroup id subnets publicSubnetsIds apply ids = gt ids ``` Thanks a bunch < magnificent lifeguard 15082>

`publicSubnetsIds apply ids = gt ids ` is the same as just `publicSubnetsIds`
