Answered! I added the redux-observable tag to it too, which is the only tag I subscribe to. 😄

@ghasemikasra39 That may or may not be related to your epics, but regardless it is likely truthful--you are dispatching something that is not a plain object. In this person's case they were simply missing a return statement, so undefined was what is being dispatched. But your case may well vary.

Your best bet is to pause your debugger when this happens, walk the stack back until you can see what in fact is being dispatched and from where. If you need help, your best bet is to create a small, simple reproducible piece of code you can share on Stack Overflow--you might even discover the cause in the process of doing so.

Dear @jayphelps
When I pass in an async function to the mergeMap, and fetch my token out of my AsyncStorage, I get this error. But when I pass in a normal function, Everything works(I use static token though). I don't think it has something to do with my action.

@ghasemikasra39 Please don't post new questions in old, closed issues. Your question will be hard to notice and it's unlikely to be related.

Can you ask the question on stack overflow, our gitter channel or the rxjs channel in the reactiflux discord? Until we can enable github discussions for this repo it's also fine to create a new issue. Please include the code that is giving you this error.
