Error while trying to run 2 sagas at a time

sareek commented 5 years ago

SOLVED!

The issue was with default keyword on the documentation in saga. While starting more than one Sagas at a time in documentation it is written as,

export default function* rootSaga() {......

It should be,

export function* rootSaga() {

SOLUTION! *As you export function as default in sagas.js as follows;

export default function* rootSaga() {
  yield all([
    helloSaga(),
    watchIncrementAsync()
  ])
}

*You should change the import statement in main.js from: import { rootSaga } from './sagas'; to: import rootSaga from './sagas';
