The REST API route definition for wp-post-modal/v1/any-post-type is missin

Hi,
Same issue on me.
It works with a page slug:
https://site.com/wp-json/wp-post-modal/v1/any-post-type?slug=any-page-slug

But it’s not working with a CPT slug.:
https://site.com/wp-json/wp-post-modal/v1/any-post-type?slug=any-cpt-slug

Thanks yes I see. No idea what’s the problem. The situation is the same in both local and hosting. Anyway, default method is working fine.

Here is my debug log:

PHP Notice: register_rest_route was called incorrectly. The REST API route definition for wp-post-modal/v1/any-post-type is missing the required permission_callback argument. For REST API routes that are intended to be public, use __return_true as the permission callback. Please see Debugging in WordPress for more information.
