Type for query with 0 parameters

[ChuckJonas]

I'm trying to figure out how to define a query that has no parameters.

I can do something like this:

getPosts: builder.query<WorkItem[], void>({ ... })

and I can then call useGetPostsQuery().

However, I cannot pass the second parameter for options if I do this:

useGetPostsQuery({refetchOnFocus: true})
//Argument of type '{ refetchOnFocus: boolean; }' is not assignable to parameter of type 'void | unique symbol'.
  Type '{ refetchOnFocus: boolean; }' is not assignable to type 'unique symbol

Is there a proper way to define a query with any params?

You always have to pass a "query cache key" as the first arg to a useQuery() hook. In this case, the correct cache key would be undefined. So: useGetPostsQuery(undefined, {refetchOnFocus: true}).
