Since the current Registry REST API did not implement the pagination right now, If the user specifies any value other than 0 for the pagestart or pageend in the REST requests will throw HTTP 404 error code. Even though the user omits the pagestart and pageend parameters to be passed with URL , the request will work with the current REST API. Pagination support to REST API will be adapted soon. |
