I follow the official example aws-ts-stackreference (https://github.com/pulumi/examples/tree/master/aws-ts-stackreference) with self-managed backend (locally on filesystem) (https://www.pulumi.com/docs/intro/concepts/state/#self-managed-backend). If I use the default directory

file://~

for all projects and run

pulumi up

for

company

project then

department

project, Pulumi will delete the

company

stack and create stack for

department

. If using Pulumi Backend Service, this statement works:

new pulumi.StackReference('clstokes/aws-ts-stackreference-company/dev')

where

clstokes

in the example is the Pulumi Backend Service username,

aws-ts-stackreference-company

is the project name and

dev

is the current stack. If I set backend url, so each project has a separated

.pulumi

at it's root directory

Pulumi.yaml
backend:
  url: file://./

Now, how can I get the stack reference of

company

or

department

in

team

project:

new pulumi.StackReference('???')

?

new pulumi.StackReference('clstokes/aws-ts-stackreference-company/dev')

will produces error:

pulumi:pulumi:StackReference (clstokes/aws-ts-stackreference-company/dev):
    error: Preview failed: unknown stack "clstokes/aws-ts-stackreference-company/dev"
