uncaught at check sagaMiddleware.run(saga, ...args): saga argument must be a Generator function!

After adding the new saga in sagas.js and adjusting the store to include the middleware following the tutorial

//sagas.js
export function* helloSaga() {
   console.log('Hello Sagas!')
}

the following error appears:

utils.js:188 uncaught at check sagaMiddleware.run(saga, ...args): saga argument must be a Generator function!

Both in latest Chrome and FF.

Oh, my bad, it was a long day - the issue was caused by erroneous default import, while the saga was using the named export.

@zilan830 Just using default export:

//sagas.js
export default function* helloSaga() {
   console.log('Hello Sagas!')
}
