Redux Toolkit - do not send request when query param is invalid

Question

I've checked the redux toolkit docs and don't see an example of this typical use case: do not send the request of the query has an invalid param.

For example, a get request to endpoint /categories/{name} requires a name value. If name does not have a value, then the request should not be made.

const baseQuery = fetchBaseQuery({
  baseUrl: Constants.PATHWAY_API_URL
});

export const pathwayApi = createApi({
  reducerPath: 'pathwayApi',
  baseQuery: baseQueryWithReAuth,
  endpoints: builder => ({
    getSubCategories: builder.query({
      // NETWORK REQUEST SHOULD NOT BE MADE IF "name" param is falsy
      query: name => `${Constants.PATHWAY_API.CATEGORIES_PATH_NAME}/${name}`,
    }),
  }),
});

I want to add this type of param validation to all my queries that require a param value or values. What's the recommended approach / pattern for handling this validation at the createApi (or possibly fetchBaseQuery) layer? Thanks in advance!
