When I activate your extension, you send me the form to spam

If I keep the plugin active, it gives continuous errors and it does not appear that the form is being sent. Then in the Crohme console it offers the following error:

jquery.js? ver = 1.12.4-wp: 4 POST https://xxxxxxxxxxxxxxx.es/wp-json/contact-form-7/v1/contact-forms/2355/feedback 500 (Internal Server Error)
send @ jquery.js? see = 1.12.4-wp: 4
ajax @ jquery.js? see = 1.12.4-wp: 4
wpcf7.submit @ scripts.js? see = 5.1.4: 341
(anonymous) @ scripts.js? see = 5.1.4: 56
dispatch @ jquery.js? see = 1.12.4-wp: 3
r.handle @ jquery.js? see = 1.12.4-wp: 3

* {“code”:”rest_no_route”,”message”:”No se encontr\u00f3 la ruta que coincida con la URL y el m\u00e9todo de la petici\u00f3n”,”data”:{“status”:404}}

If I continue to force the shipment it takes me to spam.

If I deactivate your plugin, everything works correctly.

Could you tell me where the conflict is?

Thank you
