If you are testing the app in the browser, try testing on the mobile. you will be facing a lot of random errors in the browser. @Timotheus

@hexation1 didn’t do any good. Pls. help. Thanks.

Double check your imports, this might also happen if you are injecting without importing @Timotheus

Yup already did. imports are complete. Still no good. @hexation1

@Timotheus Try removing constructer’s parameters one by one ( the ones you added) and see whether its working or not.

8

usually, it shows ‘?’ as the location of the parameter that has problem.

9

Yup, and it says all. Don’t know why. @hexation1

It seems that you are calling some data or something and it’s throwing an error!
Can you post your code here?

Some Component not imported in .ts file .

Stop Ionice Serve

Then
Start IONIC server . It will show error

Got it already. Had something to do with the npm package of font-awesome. So I downloaded the library instead and referenced the files in index.html

Won’t that blow your app binary up with the all the icons, even the ones you don’t use? There are much more efficient ways of using FontAwesome in Ionic apps, but the details depend on what Angular version you’re using.
