Answer 1

try this

this.http.get().pipe(
  map(res => {
   res.array.forEach(el => {
    if (el.status !== "completed") {
      //error will be catched by retryWhen
      throw res;
    }     
   })
   return res;
  }),
  retry(5),
  retryWhen(errors => errors.pipe(delay(1000)))
)

Answer 2

Not sure what your code looks like, but I think this approach should work:

src$.pipe(
  retryWhen(
    errSbj => errSbj.pipe(
      delay(/* ... */),
      take(5),

      // Until it receives a `COMPLETED` status
      takeUntil(statusCompleted$)
    )
  )
)

When statusCompleted$ emits, the entire stream will complete .
