Is that stack name correct?  Usually its something like, "myorg/projectname/test"

Hi, Thank you for the response..
I had previously referred this thread below.. When we have a self-managed backend, the organisation reference does not exist.. there was an example in C# that am trying to replicate in python for local backend
```var stackReference = new StackReference("shared", new StackReferenceArgs { Name = "demo.dev" });```

<@U020U8KUC14> or <@U0250KG98DT>
I’m trying to understand the same thing, self-managed backend (S3), how do you reference to another Stack. I’m doing some tests and getting

```pulumi:pulumi:StackReference (project_name/stack_name):
    error: Preview failed: unknown stack "project_name/stack_name"```


<@U02BDN50JRM> Did you try, org/projectname/stackname ?

<@U011A8MPQGZ> Thanks for the reply.
How/Where do I get the org name?

When you're in the console, if there's more than 1, like your username or an org your a member of,

<@U02BDN50JRM> can u try without the project name.. This worked for me,
```reference = StackReference(mystack)```

<@U0250KG98DT> I did try this option, but all the project stacks have to be on the same folder and bucket on S3, with some sort of naming convention for stack to avoid collision. But I really don’t like that approach, having all state files on just on folder and forcing a different name on stacks.

So trying to separate each project on folders, or going to use something else, Cloud Formation, I was told that could help on this.
