If all primary constructor parameters have default values, Kotlin will generate a parameterless constructor as well. In your case DateJoined is missing one. So

data class User(
        var FirstName: String = "",
        var LastName: String = "",
        var Email: String = "",
        var Password: String = "",
        var DateJoined: ... = ...
)

(I don't know which types are allowed for fields in FireBase, but Any probably isn't one and if it is it can't be efficient.)
