TypeError: Cannot read property 'invoke' of undefined

[hearot]

I was trying to code my own max function in Bosque when I got this: TypeError: Cannot read property 'invoke' of undefined.

I'm using Windows 10 and I used node bin\test\app_runner.js over.bsq to launch the script.

Output

Reading app code...
Executing app code...
fail with exception -- TypeError: Cannot read property 'invoke' of undefined

Code - over.bsq

namespace NSMain;

function max(x: Int, y: Int): Int
    ensures _return_ == x || _return_ == y;
{
    if (x >= y) {
        return x; 
    } else {
        return y;
    }
}

function main(): Int {
    var x = 10;
    var y = 20;

    return max(x, y);
}

The entrypoint function main should be annotated as such. After the changes below it runs and produces the output 20.

entrypoint function main(): Int {
    var x = 10;
    var y = 20;

    return max(x, y);
}

Fixed, thank you.
