What version of ionic are you using?

[bleuscyther]

ionic 4 beta 8,
never mind : i had to remove the "fix" for beta 5 :

this.modalController.dismiss(null, undefined, null);

[manucorporat]

this.modalController.dismiss(null, undefined);

^ null is not a valid value for the third argument, this should work
