Suddenly cannot purge more than 30 files on a single request

Previously, it was 500 files. Is it a new limit for purging or a bug? Thanks.

API Documentation (find code 1094, it still shows 500 files):

Example error response:

“result”: null,
“success”: false,
“errors”: [
“code”: 1094,
“message”: “Exceeded maximum amount of 30 files that can be purged on a single request.”

The documenation won’t have been updated in this case.
