TypeError: content.ionScrollStart.takeUntil is not a function

Hi, I am having this problem, can you help me please?

Hi @deyvijam,

What are you trying to do? What version of Ionic Angular are you using?

At first look, it seems that you’re trying to use the takeUntil operator in an observable, but the function doesn’t exist (is undefined). If you’re using the newer RxJS versions, you have to do observable.pipe(takeUntil(subscription)) and import takeUntil from rxjs/operators.
