Pulumi stacks (which exist) not appearing in `pulumi stack ls -a`

Question

I've just pulled an IaC repo with Pulumi code, and I'm trying to select my default stack, but when I run pulumi stack ls -a no stacks are listed:

% pulumi stack ls --all                                            
NAME  LAST UPDATE  RESOURCE COUNT  URL
%

When I try to select the stack outright it tells me the stack doesn't exist:

% pulumi stack select <org>/<project>/delta
error: no stack named 'delta' found
%

Which is particularly frustrating, because if I try to create a stack named delta I get:

% pulumi stack 
Please choose a stack, or create a new one: <create a new stack>
Please enter your desired stack name.
To create a stack in an organization, use the format <org-name>/<stack-name> (e.g. `acmecorp/dev`): delta 
Please enter your desired stack name.
error: stack '<org>/<project>/delta' already exists
%

Clearly, I'm missing something. What is it?

Answer 1

It seems that some IT genius made an account for me in Pulumi but didn't add me to any groups ergo I can't see any of our stacks. The Pulumi web UI is a little broken though, so I'm able to see the index of stacks by merely being a member of the organization; when I click on any stack I get a 404 page for the stack details. The index showing the stack made me believe I had privileges.
