try using

requireOutput

instead of

getOutput

I added

.apply

in the output, but the error still same.

Based on the error message it seems that the

infra

stack is having a problem exporting the output due to

secgroup

or

subneta

being undefined. It is not clear which one is the issue without seeing more code.

Hello @clever-sunset-76585, sorry I just push example code into github https://github.com/handrywahyudi/infra-using-pulumi. Maybe there is something wrong on my code. Thank you.

Thanks for putting up the code on GH. If I understood what you are trying to do, it seems that you have two stacks from the same codebase that creates different resources based on the stack name. That's certainly a unique way of doing it. Why not have the two stacks as two separate Pulumi projects instead? The way you are trying to access the vpc export from your

vpc.ts

won't work because you have the variable in that file guarded by an if-condition that would only be true when this stack is

infra

. When you are running as the

dev

stack it will be

undefined

. So the issue doesn't seem to be because of stack references. It's an issue with line 7 in your

index.ts

file at the root of your repo. To make it work you could change it to add an if-condition in

index.ts

too to see what the current stack is. Structuring your app the way you have it now is confusing to be honest. Is there a reason you do not want to have the infra stack as its own Pulumi project? The code is likely to get more complicated with more conditional branches all over the place the way it is right now. Have a look at the

examples

repo for comparison of how to have multiple Pulumi projects within the same folder.

Haha sorry, I am not follow the structure of file pattern, because I just want to save my resource (even though different env ) in one folder and I have vpc for global that used by different env resource. So the point is my code isn’t work because if-else condition in stack? and I need to restructure the code to separate the resource in different pulumi project at each folder. let me try first. Thank you for your advice @clever-sunset-76585

Well, to be precise, the reason your code isn't working is because the if-condition in

vpc.ts

only runs when your stack name is

infra

. So when you run the same code for your

dev

stack, the export in that file is never assigned a value even though the vpc does get created in the

infra

stack. There is a way to get it to work but honestly I think you'll find it more confusing to work with it over time.

I restructured the code like this https://github.com/handrywahyudi/infra-using-pulumi and created project to each folder. It works 😁 Thank you, really appreciated 🙏

Great! 🎉👏
