Hello, Can somebody please help with printing/accessing in debugger list of AWS subnets? I'm stuck (( Here is how I get list of the subnets, but I don't understand on how to print that list and how to access it's values in the debugger (I'm using vscode)

const aws = require("@pulumi/aws");

const tagsPrivate: { [key: string]: string } = {
  EKS_Cluster: eksOpts.name,
  Type: 'private'
};

const privateSubnetIds = aws.ec2.getSubnetsOutput(tagsPrivate).apply(sn =>  sn.ids);

// this doesn't work, I'm getting "Private subnet IDs: Calling [toString] on an [Output<T>] is not supported."
<http://pulumi.log.info|pulumi.log.info>(`Private subnet IDs: ${privateSubnetIds}[0]`);

Thanks

Put the log inside an apply:

privateSubnetIds.apply(ids => <http://pulumi.log.info|pulumi.log.info>(`Private subnet IDs: ${ids}[0]`))

wow, that worked, thanks a lot! Do you know why this syntax works and my form didn't?

Because as the error message says you can't meaningfully call toString on an Output<T>. An output is kind of like a promise so you have to wait for it's result (by using apply).

Right, so you mean that this

aws.ec2.getSubnetsOutput(tagsPrivate).apply(sn =>  sn.ids)

will not really return list of ids ?

It will return an Output of a list of ids

I see, thanks a lot

Awesome! 🙇‍♂️
