Bug report: Error in console after 4.8.1 update

Im getting this error in the console: /wp-json/contact-form-7/v1contact-form-7/v1/contact-forms/24704/refill Failed to load resource: the server responded with a status of 404 ().

I’ve rolled back to the previous version (4.8) and it’s working without troubles.

I’ve no custom code added to the plugin.

Thank you!
