-- | An exception was thrown for a validation issue. Review the available
-- parameters for the API request.
_ValidationException :: AsError a => Getting (First ServiceError) a ServiceError
_ValidationException = _ServiceError . hasCode "ValidationException"

-- | Failed access to resources caused an exception. This exception currently
-- only applies to < DescribeScalingPolicies>. It is thrown when
-- Application Auto Scaling is unable to retrieve the alarms associated
-- with a scaling policy due to a client error, for example, if the role
-- ARN specified for a scalable target does not have the proper permissions
-- to call the CloudWatch
-- <http://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_DescribeAlarms.html DescribeAlarms>
-- API operation on behalf of your account.

-- | Concurrent updates caused an exception, for example, if you request an
-- update to an Application Auto Scaling resource that already has a
-- pending update.

-- | The service encountered an internal error.
_InternalServiceException :: AsError a => Getting (First ServiceError) a ServiceError
_InternalServiceException = _ServiceError . hasCode "InternalServiceException"

-- | The specified object could not be found. For any 'Put' or 'Register' API
-- operation, which depends on the existence of a scalable target, this
-- exception is thrown if the scalable target with the specified service
-- namespace, resource ID, and scalable dimension does not exist. For any
-- 'Delete' or 'Deregister' API operation, this exception is thrown if the
-- resource that is to be deleted or deregistered cannot be found.
_ObjectNotFoundException :: AsError a => Getting (First ServiceError) a ServiceError
_ObjectNotFoundException = _ServiceError . hasCode "ObjectNotFoundException"

-- | Your account exceeded a limit. This exception is thrown when a
-- per-account resource limit is exceeded. Application Auto Scaling has a
-- limit of 40 scalable targets per account for Amazon ECS services, 50
-- scaling policies per scalable target, and 20 step adjustments per step
-- scaling policy.
