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 a retryable error messages list to the attributes map in a source. 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.
