 * @throws {@link AccessDeniedException} (client fault)
 *  <p>Access is denied because either you don't have permissions to perform the requested operation or MediaPackage is getting throttling errors with CDN authorization. The user or role that is making the request must have at least one IAM permissions policy attached that grants the required permissions. For more information, see Access Management in the IAM User Guide. Or, if you're using CDN authorization, you will receive this exception if MediaPackage receives a throttling error from Secrets Manager.</p>
 *
 * @throws {@link InternalServerException} (server fault)
 *  <p>Indicates that an error from the service occurred while trying to process a request.</p>
 *
 * @throws {@link ThrottlingException} (client fault)
 *  <p>The request throughput limit was exceeded.</p>
 *
 * @throws {@link ValidationException} (client fault)
 *  <p>The input failed to meet the constraints specified by the AWS service.</p>
 *
 * @throws {@link MediaPackageV2ServiceException}
 * <p>Base exception class for all service exceptions from MediaPackageV2 service.</p>
