Wondering why I can't catch this assertion error

gistfile1.txt

var assert = require('assert');
var EventEmitter = require('events').EventEmitter;
    
var TestEmitter = function() {
    var self = this;
    EventEmitter.call(this);
    setTimeout(function() {
        self.emit('any', false);
    }, 2000);
};
TestEmitter.prototype = Object.create(EventEmitter.prototype);

var funcThatThrowsAssertionError = function(fn) {
    var testEmitter = new TestEmitter();
    testEmitter.on('any', function(val) {
       assert.ok(val);
    });
    fn();
};

try {
    funcThatThrowsAssertionError(function() {
        console.log('done');
    });
} catch(err) {
    console.log(err);
}
