Still facing console error when closing modal popup by clicking on close button.

I've got the same error. It also happens when closing a confirm modal by "not confirming" (as in cancel).

I don't get the error. Hope this example helps: https://github.com/ashfaqch/angular-modal-dialog-example

This comes with Version 3.0.2 and I have Angular 4 if that helps.

Ahh, yes - per the example I was missing the onrejected callback. Previously when I was getting error:

dialogRef.result.then((result) => {
  if (result) {
    alert(`The result is: ${result}`);
  }
});

Simple adding the onrejected callback prevents the error from occurring:

dialogRef.result.then((result) => {
  if (result) {
    alert(`The result is: ${result}`);
  }
}, () => {
  return;
});

Still though, you'd expect the library to check for the presence of a onrejected callback before attempting to call it.
