Error: pulumi:providers:aws resource 'default' has a problem: Failed to refresh cached SSO credentials

Export

Fixes the Pulumi AWS provider failing when cached AWS SSO credentials expire. For engineers using AWS SSO whose previously working stack starts failing at preview, the fix is re-authenticating with the AWS CLI.

Error: pulumi:providers:aws resource 'default' has a problem: Failed to refresh cached SSO credentials

TL;DR

Your cached AWS SSO token expired. Run aws sso login (with --profile [profile] if you use one), then re-run pulumi preview. For CI or long-lived setups, move to Pulumi ESC with AWS OIDC dynamic credentials.

The error

Diagnostics:
  pulumi:providers:aws (default):
    error: pulumi:providers:aws resource 'default' has a problem: Failed to refresh cached SSO credentials.
    Please refresh SSO login.

Fix it

  1. Re-authenticate: aws sso login (or aws sso login --profile [profile]).
  • Success check: the browser flow completes and the CLI reports a successful login.
  1. Verify the refresh worked: aws sts get-caller-identity --profile [profile].
  • Success check: it prints your identity instead of an SSO error.
  1. Re-run pulumi preview or pulumi up.
  • Success check: the provider configures and the operation proceeds.
  1. If this keeps recurring in automation, replace SSO-cache auth with Pulumi ESC dynamic credentials via AWS OIDC.
  • Success check: unattended runs stop failing on SSO expiry.

When to use this

You hit this on a stack that used to work with AWS SSO, and the only thing that changed is time passing.

When NOT to use this

Do not use this for No valid credential sources found (nothing configured) or ExpiredToken on manually exported session keys (refresh those keys instead).

Compatibility

Pulumi CLI 3.x, Pulumi AWS provider v6.x, AWS CLI v2 with SSO configured.

Variants

  • error: pulumi:providers:aws resource 'provider' has a problem: Failed to refresh cached SSO credentials.
  • Unable to locate credentials (bare; check how the project authenticates before guessing)

Root cause

AWS SSO tokens are short-lived. The provider reads the SSO token cache written by aws sso login; once it expires, refresh fails and provider configuration errors out. Pulumi cannot trigger the interactive SSO flow itself.

Edge cases

  • Multiple profiles: make sure you log in to the profile your stack actually uses (aws:profile in stack config).
  • In containers or CI there is no browser for the SSO flow. Use OIDC or static credentials there.
