Error message in Query Monitor

Hi there,

I’ve ver 2.0.3 installed. This is just to inform you, that I see the following query monitor alert when editing posts:

Message Function register_rest_route was called incorrectly. The REST API route definition for wp-rollback/v1/fetch-info is missing the required permission_callback argument. For REST API routes that are intended to be public, use __return_true as the permission callback. (This message was added in version 5.5.0.)

Caller register_rest_route()
