SecurityError : DOMException code 18

[DoyeongJoo]

First, thank you for providing this great code.

I divided this source into client and server parts. The server part uses the existing NodeJS code, and the client part is handled using the code ajax in tomcat6 version. However, DOMException code 18: Security Error is output after executing navigator.credentials.create () function. I searched for the problem, but there is no clear answer.

If you see this message, please reply.
