How should I configure the Pulumi platform access token using the Automation API? What I have now:
`stack.Workspace().SetEnvVar("PULUMI_ACCESS_TOKEN", req.Source.Token)`
But I still get this error:
`error: PULUMI_ACCESS_TOKEN must be set for login during non-interactive CLI sessions`

Curious about this too.  For C# I had to set that env bar before running the app.

oh interesting, <@U01038HJ93R> do we know if this should work? it sounds like the env var isn't get pushed to the forked process?

Hmm… you might also have to set the `PULUMI_BACKEND_URL` env var to `<https://app.pulumi.com/>&lt;your-org&gt;`

<https://www.pulumi.com/docs/intro/concepts/state/#29e06380-0aff-4d3e-b29f-3ddc3dd4f7a2:~:text=PULUMI_BACKEND_URL|link to docs>

<@U01038HJ93R> applied this: <https://github.com/ringods/pulumi-resource/commit/486900cffb94f3a499092170fd651cbe97eb4153>
with the same result:
`error: PULUMI_ACCESS_TOKEN must be set for login during non-interactive CLI sessions`

token &amp; organization are passed from Concourse itself. See an example of a pipeline configuration in the README:
<https://github.com/ringods/pulumi-resource/#full-example>

okay figured it out. The env vars need to be set for the creation of the stack itself, so you gotta pass it in as a `LocalWorkspaceOption`

```stack, err := auto.UpsertStackLocalSource(
    ctx, 
    stackName, 
    r.PulumiSourceLocation, 
    auto.EnvVars(map[string]string{"PULUMI_ACCESS_TOKEN": req.Source.Token}),
)```

ignore what I said about the backend_url thing coz you don’t need that, just the access token. It just needs to be set prior to the stack being created, so passing it in as a localworkspaceoption attaches the env var when creating the workspace for the stack

<@U01038HJ93R> should I set `PATH` also via `LocalWorkspaceOption`?

<@U01038HJ93R> Progress. I get another error now. So I guess your suggestion worked! Tnx.
