Camunda Welcome Login credentials error

I built Camunda- Spring boot based project as per your youtube video tutorial

I ran Camunda- Spring boot based project in Eclipse & I started localhost:8080 to open Camunda Welcome in my system.
I entered username: demo & password: demo

I am unable to login, it’s showing wrong credentials

I’m also attaching application.yaml properties file screenshot for reference

Please solve issue.

What version of java are you running?
