console.log() not showing in any browser in angular 6 project

Question

This is an ongoing angular OTA project. All the logging worked before, until suddenly they stopped working. None of the previously written console.log are outputting anything in the browser console.

ngOnInit() {
    console.log('Hiiiii');
    this.imgUrl = this.allapi.imageUrl;
    this.journeyType = JSON.parse(sessionStorage.getItem('journeyType'));
    this.bookingData = JSON.parse(sessionStorage.getItem('payload'));
    if (this.bookingData.FareBreakdown.length > 0) {
      this.fareBreakDown = this.bookingData.FareBreakdown;
    } else {

    }
    this.calculateLayover();

    sessionStorage.setItem('promoApplied', JSON.stringify(this.promoApplied));

    if (this.journeyType == 3) {
      this.layover_multi = JSON.parse(sessionStorage.getItem('layoverMulti'));
      this.multiCityPlaces = JSON.parse(sessionStorage.getItem('multi_places_list'));
    }
    this.getFareBreakDown();
  }

In the ngoninit() the first console.log is not showing any output in the browser.

@SudhirOjha that is not the case I think. Not only ngOnInit(), none of the function's consoles are displaying anything, which previously worked fine btw. — Sourav Bhowmik, May 14 '19 at 05:09
@SouravBhowmik Is it possible to provide a stackblitz where *I/we* can reproduce it? — Prashant Pimpale, May 14 '19 at 05:18
@Mindless No man, it's enabled. My other projects are showing consoles on chrome. — Sourav Bhowmik, May 14 '19 at 05:25
@PrashantPimpale I don't think so :( . But I am trying. Is there any system files of angular that I can provide to you? For better understanding maybe? — Sourav Bhowmik, May 14 '19 at 05:27
@SouravBhowmik Not duplicate but have a look on [this](https://stackoverflow.com/questions/10257301/where-to-read-console-messages-from-background-js-in-a-chrome-extension) — Prashant Pimpale, May 14 '19 at 05:37
add `debugger;` after `console.log('Hiiiii');` and refresh the page.I think your page not fired. — Muhammet Can TONBUL, May 14 '19 at 05:39
@PrashantPimpale I already checked it. It was a chrome extension file, they logged it using chrome extension's developer mode. I can't do that in an angular project, can i? — Sourav Bhowmik, May 14 '19 at 05:45
it doesn't matter what they are using, you have some projects showing the log and some don't, so i don't think its a matter of extension — Mindless, May 14 '19 at 05:46

In your index.html, <script src="https://scripts.sandbox.bka.sh/versions/1.0.0-beta/checkout/bKash-checkout-sandbox.js"></script> this line broke your code. Because override console.log function in this js. Remove this script if you dont use.

Thanks a lot man ! It worked. Can you please explain, why this worked? – Sourav Bhowmik May 14 '19 at 07:36
If you review the contents of the ".js" file above, you will see that many functions of the "console" object are "overrided" in this file. For example, `console.log = function (args) { this.cacheargs = args; return null; } `. – Muhammet Can TONBUL May 14 '19 at 07:41

checked them already. It's just as you have shown in my browser too, its labelled as default. I have 5/6 similar types of angular projects. I am facing this problem in some of them, others are working fine – Sourav Bhowmik May 14 '19 at 05:23
Can you show abit more of the code? I don't see anything wrong with this code, what if you remove rest of the code and just leave ngOnInit() { console.log('hi'); } – Mindless May 14 '19 at 05:26
Makes no difference. It's not a matter of one perticular component rather of the whole project. – Sourav Bhowmik May 14 '19 at 05:52
well that's why we ask you to post more code – Mindless May 14 '19 at 05:53
