I m having some more Output fun I ve exported the publicSubn

Question

I m having some more Output fun I ve exported the publicSubnetIds from an EKS stack with a line like `export const publicSubnetIds = cluster core publicSubnetIds ` and then import them into another stack with `const pubsub = stackMon getOutput publicSubnetIds ` I then need to use them to annotate an ingress in a helm chart something like ```ingress annotations `$ pubsub 0 $ pubsub 1 ```` or ``` `$ pubsub join ```` but this results in `Property join does not exist on type OutputInstance lt any gt ` or a similar error saying I can t index an Output lt any gt with 0 or 1 What am I getting wrong here Can I not export an array Do I need some apply magic on the gotten output before Typescript will accept it is and array and can be joined

I believe `getOutput` returns an object of type `Output`

You could either try using `getOutputValue` instead or do `pubsub apply value = gt your code that uses the value 0 here `

```const pubsub = stackMon getOutput publicSubnetIds const grafana = pulumi all pubsub apply subnet1 subnet2 = gt return new k8s helm v3 Release grafana values ingress annotations <http alb ingress kubernetes io subnets|alb ingress kubernetes io subnets> `$ subnet1 $ subnet2 ` ``` I ve removed some static config lines to make it clearer Now pubsub is an Output lt any gt which contains and array of 2 strings or will contain that at runtime when it s looked up and when I try and run this I get ``` index ts 132 28 error TS2769 No overload matches this call The last overload gave the following error Argument of type Output lt any gt is not assignable to parameter of type unknown Type OutputInstance lt any gt is missing the following properties from type unknown length pop push concat and 29 more index ts 132 44 error TS7031 Binding element subnet1 implicitly has an any type index ts 132 53 error TS7031 Binding element subnet2 implicitly has an any type ``` any ideas

`const publicSubnetIds = pubsub apply list = gt list join `

is what it took in the end

Ah no that gives me `Calling toString on an Output lt T gt is not supported `

Ok for the sake of anyone who ends up looking for the answer here ```const pubsub = stackMon getOutput publicSubnetIds const pubsubId = pubsub apply l Array lt string gt = gt return l map a = gt `$ a ` join const grafana = new k8s helm v3 Release grafana values ingress annotations <http alb ingress kubernetes io subnets|alb ingress kubernetes io subnets> pulumi interpolate `$ pubsubId ` ``` Is what actually manages to get the annotation to work D
