Fix ExpiredTokenException

✅ Solution

The "ExpiredTokenException" in Vault usually arises from Vault's authentication tokens or AWS credentials used by Vault (e.g., for KMS or Roles Anywhere) expiring before Vault can refresh them. To fix this, increase the token TTL (time-to-live) for Vault's authentication methods or the allowed credential duration in AWS IAM roles used by Vault and ensure Vault's token refresh processes are properly configured and functioning. Consider also configuring Vault's `max_retries` and `retry_interval` parameters for AWS operations to handle intermittent credential unavailability.
