The following data is returned in JSON format by the service.
Errors
For information about the errors that are common to all actions, see Common Errors.
- ClientException
-
These errors are usually caused by a client action. This client action might be using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Or, it might be specifying an identifier that isn't valid.
The following list includes additional causes for the error:
-
The
RunTask
could not be processed because you use managed scaling and there is a capacity error because the quota of tasks in thePROVISIONING
per cluster has been reached. For information about the service quotas, see Amazon ECS service quotas.
HTTP Status Code: 400
-
- ClusterNotFoundException
-
The specified cluster wasn't found. You can view your available clusters with ListClusters. Amazon ECS clusters are Region specific.
HTTP Status Code: 400
- InvalidParameterException
-
The specified parameter isn't valid. Review the available parameters for the API request.
HTTP Status Code: 400
- ServerException
