Does this stack &amp; the one it is referring are in the same org?

From the error it seems as if the stacks are still not part of the org, maybe you can try a pulumi up/refresh on the stacks which are being referred here first

Unfortunately that didn't work. The only thing that seems to work is deleting the stack ref from the stack state

Yes that would work but if this ref is coming from the code then won't it come back again if you run pulumi up/preview?

also for reference we need orgname/stack-name are you doing the same?

What do you see when you do `pulumi stack ls` from the project?

`pulumi:pulumi:Stack               oncall-slackbot-dev`   here your stack name is showing as `oncall-slackbot-dev`  this is `<project-name>-<stack-name>` so your project name is `oncall-slackbot` ? and stack is `dev` right?

But `View in Browser (Ctrl+O): <https://app.pulumi.com/myorg/myapp/dev/previews/22c0041d-fd3a-4ada-b7c3-b24131d83706>` this is showing `myapp/dev`

I am guessing if the projects `myapp` &amp; `oncall-slackbot` are in the same org?

you need to do `pulumi refresh --yes` first to update the stack reference in the state & then update the code if `pulumi refesh --yes` doesn't work then there are definitely some issues around referencing

Sorry yeah I failed to replace all the names but those projects were in the same org. Refreshing failed because the stack with the old org name wasn't found but once I deleted it from the state it worked.

Updating the state per stack seems to be working although it's a bit cumbersome so far
