问题 I am learning taking this testing course to test connected components by setting up a store factory test helper that 'creates a store for testing that matches the configuration of our store'. Below, you can see my connected sample component as well as the code used to setup tests, in which I create a connected, shallow enzyme wrapper of my sample component.

(for my specific use case, I want to listen to

问题 I need to have a global Error object in my app state. So I created an http interceptor to dispatch setError action: export interface IlgError { message: string; responseError: HttpErrorResponse; } export const setError = createAction("[Global] Error Occurred", props<{ errorObj: IlgError }>()); but when I dispatch I get the error: Error: Detected unserializable action at "errorObj.responseError" My settings for app module: StoreRouterConnectingModule.forRoot({ routerState: RouterState.Minimal

问题 I have been using React Native for a few years and have only recently needed to utilise Redux on a new, more complex project. I am currently in the process of following a number of tutorials trying to work my way through the basics. I am currently stuck with the following error: Invariant Vilation: Could not find "store" in either the context of props of "Connect(App)" I have found a number of posts with information about this error but because of the low amount of knowledge I currently have,
