Amazon Alexa Integration

Hello !

Does Alexa Echo Dot (3rd Gen) works with Smart Lock?
I just activate from app Smart Lock an account to Activate Nuki Web.
On the www.web.nuki.io can open and close the door.
Smart lock was added to Alexa.
When I tap on icon lock from Alexa app, app write a message: “There is a problem with Home door. Please check on your lock”.
When I say to Alexa Open the door, and say the code, Alexa say “Open door” and the door does not open.
Can someone help me ?
