When I call createEpicMiddleware(epic) function on Angular2+,
there is an error:
"error TS2560: Value of type '(action$: any) => any' has no properties in common with type 'Options'. Did you mean to call it?"
Even if using the sample official code on https://redux-observable.js.org/ online live example, there is an error exactly same of above.
It seem to be error on createEpicMiddleware function's parameter's type error.
How can I solve this problem?
