Errors
For information about the errors that are common to all actions, see Common Errors.
- AccessDeniedException
-
Access denied or directory not found. Either you don't have permissions for this directory or the directory does not exist. Try calling ListDirectories and check your permissions.
HTTP Status Code: 403
- DirectoryNotEnabledException
-
Operations are only permitted on enabled directories.
HTTP Status Code: 400
- InternalServiceException
-
Indicates a problem that must be resolved by Amazon Web Services. This might be a transient error in which case you can retry your request until it succeeds. Otherwise, go to the AWS Service Health Dashboard
site to see if there are any operational issues with the service. HTTP Status Code: 500
- InvalidArnException
-
Indicates that the provided ARN value is not valid.
HTTP Status Code: 400
- InvalidNextTokenException
-
Indicates that the
NextToken
value is not valid.HTTP Status Code: 400
- LimitExceededException
-
Indicates that limits are exceeded. See Limits for more information.
HTTP Status Code: 400
- NotNodeException
-
Occurs when any invalid operations are performed on an object that is not a node, such as calling
ListObjectChildren
for a leaf node object.HTTP Status Code: 400
- ResourceNotFoundException
-
The specified resource could not be found.
HTTP Status Code: 404
- RetryableConflictException
-
Occurs when a conflict with a previous successful write is detected. For example, if a write operation occurs on an object and then an attempt is made to read the object using “SERIALIZABLE” consistency, this exception may result. This generally occurs when the previous write did not have time to propagate to the host serving the current request. A retry (with appropriate backoff logic) is the recommended response to this exception.
HTTP Status Code: 409
- ValidationException
-
Indicates that your request is malformed in some manner. See the exception message.
HTTP Status Code: 400
