Cannot create a modal


I get this when I try to create and present a modal:

ERROR TypeError: Cannot read property ‘create’ of undefined

my code:
openModal(table_name?) {
let myModal = this.modalCtrl.create(ModalPage, {bundle: this.bundle, table_name: table_name, appendix: “/list”});
myModal.onDidDismiss(data => {
// console.log("the choosen one: ", data);
message: 'Button: '+ data,
duration: 5000
I swear it uset to work, I did not change a thing, at one poit this error shows up,

Looks as though you’re injecting ModalController incorrectly. What’s the method signature of your constructor?
