USD - New CRM Page is not Working

Hi,

In my implementation(Configuring from scratch), when I click on a button from Contact, on click of a button, I am calling an action which will open a new case with Customer Data prepopulated on New case form.

Below are events that triggered after clicking the button.

But in USD, Case Hosted Control s opening with empty page.

I have did the same implementation in another environment, where Sample Configuration data was installed and it worked fine. See the below events that triggered after clicking the button.

So many events triggered in my environment, where I have sample data configuration. What have I missed? Can anyone help?

Thanks
