Webstorm is complaing about createEffect function argument.

[AhmedBenyahia]

I have this code in my application that is highlighted in red. I could not resolve it without adding a type to the arrow function.
I am not sure if this is a problem with ngRx or Webstorm. I tried common solutions like deleting node_module.

My Ngrx dependencies

"@ngrx/effects": "13.0.2",
    "@ngrx/store": "13.0.2",
    "@ngrx/store-devtools": "13.0.2"

The error displayed

Argument type () => Observable<TypedAction<string> | ({searchResults: RpmSearchResults} & TypedAction<"[RPM] Search eUICC records success">)> is not assignable to parameter type () => (Observable<TypedAction<string> | ({searchResults: RpmSearchResults} & TypedAction<"[RPM] Search eUICC records success">)> & ConditionallyDisallowActionCreator<DispatchType<EffectConfig>, Observable<TypedAction<string> | ({searchResults: RpmSearchResults} & TypedAction<"[RPM] Search eUICC records success">)>>)   Type Observable<TypedAction<string> | ({searchResults: RpmSearchResults} & TypedAction<"[RPM] Search eUICC records success">)> is not assignable to type Observable<TypedAction<string> | ({searchResults: RpmSearchResults} & TypedAction<"[RPM] Search eUICC records success">)> & ConditionallyDisallowActionCreator<DispatchType<EffectConfig>, Observable<TypedAction<string> | ({searchResults: RpmSearchResults} & TypedAction<"[RPM] Search eUICC records success">)>>     Type Observable<TypedAction<string> | ({searchResults: RpmSearchResults} & TypedAction<"[RPM] Search eUICC records success">)> is not assignable to type Observable<TypedAction<string> | ({searchResults: RpmSearchResults} & TypedAction<"[RPM] Search eUICC records success">)> & "ActionCreator cannot be dispatched. Did you forget to call the action creator function?"

Do you have a shareable reproduction @AhmedBenyahia ?
As far as I know there is no problem with WebStorm.
Did you also try VSCode?

I suppose that there's something wrong with the code, but I'm not sure.
You have to make sure that all paths return an Action, I'm suspicious of this.showError.

I can't reproduce either

This is the code for the showError function. It does return an action. All the effects actually have this error not just this one.
