Hi,
I have same situation - load only 2nd page and then no event occured.
script code:
doInfinite($event) : Promise {
...
}
and html:

I needed to change HTML code to (added $event.waitFor...):

And now it is working.

I tried your suggestion, but there was a mistake.

Once the disabled property is made true, we are unable to make it false.
As specified in docs,

export class InfiniteScrollExample {
  @ViewChild(IonInfiniteScroll) infiniteScroll: IonInfiniteScroll;

  constructor() {}

  loadData(event) {
    setTimeout(() => {
      console.log('Done');
      event.target.complete();

      // App logic to determine if all data is loaded
      // and disable the infinite scroll
      if (data.length == 1000) {
        event.target.disabled = true;         <------------ (a)
      }
    }, 500);
  }

  toggleInfiniteScroll() {
    this.infiniteScroll.disabled = !this.infiniteScroll.disabled;
  }
}

this.infiniteScroll.disabled = !this.infiniteScroll.disabled; <----- Not working.

try this:
(b) console.log(this.infiniteScroll);
(c) console.log(this.infiniteScroll.disabled);

the disabled property in both consoles (b) & (c) will differ once it's made true (a).

Is there any update with this? I'm having the same issue and none of the steps above seem to work?

Same issue here, $event.waitFor() workaround doesn't seem to work either.

Anything planned for correction, or other workaround ?

Thanks.

check this one out #17372

I was having the same issue. The load of the first page went well. Then the event was fired, which triggered the loading of the second page, which happened, but the loader never finished, and was unable to raise the event another time. The reason: I found out I was not calling event.target.complete() in my async callback, after adding the newly fetched data to the array. Once I did that, the thing worked like a charm.

public loadMoreData(event: any) {
    this.apiService.getMoreData().subscribe(data => {
        this.localData = this.localData.concat(data);
        event.target.complete(); // Muy importante! 
    });
}
