Non-string action types are reported `<UNDEFINED>`

You can use anything as an action type, but it seems like only strings are logged properly.

For example if you have LOAD_USER = Symbol('load user'); and then dispatch({ type: LOAD_USER }), it will log the action as <UNDEFINED>.

The action type should be logged as String(action.type).

Use serialize parameter for that:

const store = Redux.createStore(reducer, window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__({
  serialize: true
}));

See API docs for more details.

I actually was trying to do the way you suggested in redux-devtools-instrument, but that was causing issues when recomputing actions.

I’m having a similar issue, but some of my Symbol action types are being logged.

We have passed serialize as an option:

Any ideas on what might cause this? 😃
