Steps to reproduce:

I wrote this simple snippet:

confirm() {
var options = {
title: 'my title',
message: 'my message',
okButtonText: "OK",
cancelButtonText: "Cancel"
};
dialogs.confirm(options).then(function (result) {
console.log(result);
console.log("Type of result: " + typeof(result));
console.log("result is "+result);
}).catch(e => {
console.log(e);
});
}

Expected result:

show the confirm dialog

Actual result:

Exception is thrown:
