Hello guys. I am using kotlinx.serialization in my ktor api and have a data class as below.

@Serializable
data class User(
  var email: String = "", 
  @JsonIgnore var password: String = ""
)

Which annotation can i use on the password field to ignore it "only" in the http response but not within the application.
For example
Ignore it when:

get {
    call.respond(User("email", "some password"))
}

Don't ignore it when:

fun checkUserPassword(email: String) {
    val user = getUserPasswordFromDatabaseByEmail<User>(email)
    // The print below does not work (I want it to work since it is not yet part of the response)
    println(user.password)
}

And using 2 different classes? One with pass and another without it?

That is what i had thought of. I didn't want to create another class but i guess it is the only option now.

This is the simplest idea that comes to mind:

get {
    call.respond(User("email", "some password").copy(password = ""))
}

you could even encapsulate the copying with empty values in an instance method or extension function declared in the router file/module.
