Amazon Textract uses Amazon Augmented AI (A2I) to run the human review workflows that you specify in HumanLoopConfig. A2I entered maintenance mode in July 2026 and no longer accepts new customers. If your account is not an existing A2I customer, requests fail with an InvalidParameterException. For more information, see AWS service availability. If you're an existing A2I customer but receive this error, contact AWS Support and request assistance from the A2I team.
