Error: None of the following functions can be called with the arguments supplied

My class: 

class Manager (var name: String, var nationality: String) {

    constructor(agent: String): this() {}
}

returns the following error: 

None of the following functions can be called with the arguments supplied.

<init>(String) defined in Manager
<init>(String, String) defined in Manager

Any idea why?

Your class has a primary constructor that takes two arguments, and then you define a secondary constructor that takes one argument.

Now, as per the Kotlin documentation:

If the class has a primary constructor, each secondary constructor needs to delegate to the primary constructor, either directly or indirectly through another secondary constructor(s).

You're trying to do that by calling this(), but since you don't have a zero-argument constructor (primary or secondary), this results in a compilation error.

To fix, for example, you can call your primary constructor from your secondary constructor as follows:

class Manager (var name: String, var nationality: String) {
    constructor(agent: String): this(agent, "") {}
}
