getting selected stack: %w

Error message

getting selected stack: %w

What it means

After the stack reference parses successfully, the CLI calls backend.GetStack to fetch the stack metadata; this error wraps any backend error from that call. It means the backend itself failed (network/auth/API), distinct from a stack simply not existing (which yields StackNotFoundError).

Solutions

1. Retry the command — transient API/network errors often resolve
2. Re-login (`pulumi login`) to refresh credentials
3. Inspect the wrapped cause with verbose output; address 401/403/5xx accordingly
4. Verify the backend service status if errors persist

Example fix

// before
$ pulumi stack select prod
error: getting selected stack: 401 unauthorized
// after
$ pulumi login
$ pulumi stack select prod

// pre-flight credential check
if err := exec.Command("pulumi", "whoami").Run(); err != nil {
    return errors.New("refresh login before selecting a stack")
}

if err != nil && strings.Contains(err.Error(), "getting selected stack") {
    // wrapped cause may be transient; retry with backoff
    time.Sleep(2 * time.Second)
    return getStackWithRetry(ctx, ref, 3)
}

When it happens

Trigger: GetStack on the just-parsed stackRef fails — expired token, cloud API outage, or a backend returning an unexpected error for that stack identifier.

Common situations: Transient network failure right after selection, API rate limiting, stale login session, or permissions that make GetStack fail rather than return not-found.
