 ** [MaxResults](#API_ListResourceSets_RequestSyntax) **   <a name="fms-ListResourceSets-request-MaxResults"></a>

When you request a list of objects with a `MaxResults` setting, if the number of objects that are still available for retrieval exceeds the maximum you requested, Firewall Manager returns a `NextToken` value in the response. To retrieve the next batch of objects, use the token returned from the prior request in your next request.

<a name="API_ListResourceSets_Errors"></a>

For information about the errors that are common to all actions, see [Common Error Types](CommonErrors.md).

 ** InternalErrorException **   
The operation failed because of a system problem, even though the request was valid. Retry your request.  
HTTP Status Code: 400

 ** InvalidInputException **   
The parameters of the request were invalid.  
HTTP Status Code: 400
