How can break generator function by throw error inside redux saga in react

Question

I have this function inside redux-saga

function* CheckUserIsAuth() {
  try {
    const user = yield call(getCurrentUser);
    console.log(user);
    if (!user) throw new Error(null);
    const data = yield call(createUserDocument, user);
    const dataSnapshot = yield data.get();
    yield put(emailSignInSucc({ id: dataSnapshot.id, ...dataSnapshot.data() }));
  } catch (error) {
    yield put(emailSignInError(error.message));
  }
}

I want to break the try and catch error if user is null

I tried to throw error using the code above but it still went to emailSignInSucc and gave me null as string.

That means it complete function and does not break it

Answer 1

Check user and what they are returning. Perhaps user is an empty object and the error is not triggered.

If throw new Error () is called then the code will continue to run in catch
