Analysis of the compilation error in a Kotlin class

It is necessary to find out why the code below does not compile.

class Student(var name: String) {

    init {
        println("Student has got a name as $name")
    }

    constructor(section: String, var studentId: Int) : this(section) {
    }
}

Note that the constructor uses the var modifier before the parameter, and there is an attempt to call the primary constructor with the same parameter section, which causes a conflict.
