has anyone worked with the aliexpress plugin?

I’m getting this error?

Function register_rest_route was called incorrectly . The REST API route definition for a2w-api/v1/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. Please see for more information.

WordPress compatibility issue, probably… Contact the item author for the support
