[ redux-saga ] Why does a saga only run once?

Question

JavaScript

const signIn = function* signIn() {
  while (true) {
    const request = yield take(LOGIN_REQUEST);
    try {
      response = yield call(AuthService.signIn, { login: request.data.login, password: request.data.password });
    } catch (error) {
      return alert(error);
    }
    yield put({ type: SET_AUTH, username: request.data.login });
    yield put({ type: RESET_TO_MAIN });
  }
}

If the promise is rejected, an error alert is thrown, but the Saga is no longer called and does not work. What am I doing wrong?
Thank you.

When it comes to return, the function exits.
