How to cancel "all"?

[gajus]

I have the following construct:

export default function *(): Generator<*, *, *> {
  while (yield take(SET_START)) {
    const allTasks = yield all([
      fork(createRequestRoutine(GET_MOVIES, getMoviesRemote, setMovies, setError)),
      fork(watchNewSearchCriteria)
    ]);

    yield take(SET_STOP);

    yield cancel(allTasks);
  }
}

Attempting to yield cancel(allTasks) produces an error:

uncaught at rootSaga
at effects
Error: cancel(task): argument [object Object],[object Object] is not a valid Task object
(HINT: if you are getting this errors in tests, consider using createMockTask from redux-saga/utils)

It is not clear from the documentation how to cancel tasks forked using all.

Should work with yield cancel(...allTasks) or yield all(allTasks.map(task => cancel(task))). We'll try to add some docs info later.
