• Okta Identity Governance API
• Access Requests V1 API
• Okta Workflows

This may be because the user who created the token or Okta Workflows Connection was not assigned to the Access Request application.

To use the Okta Identity Governance API for any Access Request V1 actions, the user tied to the request should be assigned to the Okta Access Request application. It may be helpful to use a Service Account to create the token/connection.
