Can you provide your configuration for the createDebugger of redux- flipper middleware in your application?

If possible, can you also provide an example action type you trigger the error?

[zacdemi]

Yes, thanks.

import { createStore, applyMiddleware, combineReducers } from 'redux';
import logger from 'redux-logger';
import { composeWithDevTools } from 'redux-devtools-extension';
import thunk from 'redux-thunk';
import * as reducers from '../reducers';

const middlewares = [];

if (process.env.REACT_APP_NODE_ENV !== 'production') {
  const createDebugger = require('redux-flipper').default;
  middlewares.push(createDebugger(), thunk, logger);
} else {
  middlewares.push(thunk);
}

const appReducer = combineReducers({ ...reducers });

const rootReducer = (state, action) => {
  let nextState = state;
  if (action.type === 'USER_LOGOUT') {
    nextState = undefined;
  }
  return appReducer(nextState, action);
};

const store = createStore(
  rootReducer,
  composeWithDevTools(applyMiddleware(...middlewares)),
);

export default store;

And it happens when this action is triggered.

export const setCurrentMode = mode => async dispatch => {
  await AsyncStorage.setItem('current_mode', mode);
  return dispatch({
    type: sessionTypes.SET_CURRENT_MODE,
    payload: { mode },
  });
};

This is fixed in version 2.0.0
