Using takeEvery from redux-saga/effects causes TypeError: Cannot read property 'next' of undefined

In the latest version of redux saga (^0.16.0) I was getting a console warning about how importing takeEvery from redux-saga was deprecated and that it needed to be from redux-saga/effects.

Doing so seems to have broken rstp, and now I get the following error:

console.error node_modules/redux-saga/lib/internal/utils.js:240
      uncaught at tokenSaga at tokenSaga
       at takeEvery
       TypeError: Cannot read property 'next' of undefinedat sagaWrapper ([...]redux-saga-test-plan/lib/expectSaga/sagaWrapper.js:54:34)

switching back to the root takeEvery import works without a problem. Also worth noting that the sagas work fine outside of the test scenario.

@jfairbank Addition: if called function in effect ‘fork’ has one argument await expectSaga(myExampleSaga) .provide({ fork: effect => effect.fn(effect.args[0]), }) .run();

if called function in effect ‘fork’ has two arguments await expectSaga(myExampleSaga) .provide({ fork: effect => effect.fn(effect.args[0], effect.args[1]), }) .run();

etc

@jfairbank When I was testing sagas with effect “fork”, I have errors like:

1. ‘Cannot read property ‘next’ of undefined’
2. ‘Cannot read property ‘apply’ of undefined’

And I guess that all this errors exist, because ‘redux-saga-test-plan’ calls function in effect ‘fork’ incorrectly. I solved this problem with

await expectSaga(myExampleSaga) .provide({ fork: effect => effect.fn(effect.args[0]), }) .run();

        If I use this way, 'redux-saga-test-plan' calls function in effect 'fork' correctly. 
        
        If I don't want 'redux-saga-test-plan' calls function in effect 'fork', I use this second way (see below):
        
        `  await expectSaga(myExampleSaga)
        .provide({
            fork: (effect, next) => next,
        })`
        
        my package.json: 
        "redux-saga-test-plan": "4.0.0-rc.3",
        "redux-saga": "^1.1.3",
