Hi, I'm struggling a bit with stack references and custom backends, pulumi can't seem to find the stack I'm referencing. I'm using an azure storage container called

<azblob://pulumi-state>

all projects live in the same container and I name the stacks

<project-name>.<stack-name>

because of the limitations, a solution taken from here I've tried some different forms

<project-name>/<project-name>.<stack-name>

,

<project-name>-<project-name>.<stack-name>

,

<project-name>.<stack-name>

but nothing seems to work Any suggestions for how to reference another stack?
