Unrecognized property observed when running

[JonathanGladwin]

I have followed Wasabi Github page - https://github.com/intuit/wasabi , to install. After I installed, got localhost URL and run Swagger to test APIs.

First one I am trying with the following API,
POST : http://localhost:8080/api/v1/assignments/applications/DemoTest/experiments/ExpDemoTest/users/DemoPageUserID1?createAssignment=true&ignoreSamplingPercent=false&context=PROD&forceProfileCheck=false

Segmentation Profile :
{
"cache":true,
"payload":"green",
"assignment":"BucketA",
"context":"PROD",
"status":"NEW_ASSIGNMENT"
}

But, when I run the test, it is giving the following error:
{
"error": {
"code": 400,
"message": "Unrecognized property "cache""
}
}

Please help what is the issue here?

2. In the API reference guide, https://intuit.github.io/wasabi/v1/guide/index.html#recap
   There is "Hello World: Client Demo App" section, it is mentioned about "Admin UI" to create experiment. I couldn't get Admin UI after installation. Please advise, How to get it?

Thanks and Appreciate your help.
