Answer 1

The issue is in json to java Model mapping.
You need to rename your Model.java properties in this way:
Email -> email
FirstName -> firstName
Or add #JsonProperty("name"):
#JsonProperty("email")
private String Email;
Don't forget json changes, if you choose properties renaming:
{
"firstName":"jack",
"lastName":"testjack",
"password":"124",
"email":"emailTest#gmail.com"
}
