updatePolicy

Updates an existing policy within the AgentCore Policy system. This operation allows modification of the policy description and definition while maintaining the policy's identity. The updated policy is validated against the Cedar schema before being applied. This is an asynchronous operation. Use the GetPolicy operation to poll the status field to track completion.

If the updated policy is a temporal policy, the policy engine invalidates all active temporal sessions. If the update adds or removes temporal operators, the policy engine also invalidates active temporal sessions. For more information about temporal policy sessions, see session-based temporal policies. The policy engine returns an HTTP 409 ConflictException to in-flight sessions. To resume, you must start a new session with a new session ID.
