Connectors that support provisioning operations also have the capability to retry the operation if it fails. The retryableErrors
entry is a list of strings through which the connector searches when it receives a message from the managed application. To take advantage of this feature, add the retryable error messages list to the attributes map on an application. If one of the strings in the entry is in the error, the connector attempts to retry the connection. If the configured error string is not a part of the error message, then the connector will not attempt a retry. Add the following entry in the source XML using the SailPoint REST APIs.
