Property does'nt exist

hello everyone I’m a Beginner in Ionic and I’m trying to follow a Tutorial and did the same way in the Tutorial but I got this error

What tutorial are you following, what kind of code are you trying to use? Not really much to go on if you only post the error :slight_smile:

I’m trying to make a quotes App , I’m learning the code from Udemy
Should I post the files ? :slight_smile:

It would be helpful if you post the code you’re trying to use, yes.

is this the one by Max? what step you on?

if it is did you forget to add the import?

import {QuotesService} from “…/…/services/quotes”;

Yes it’s from Max , thank you I found My error ,
