Cannot set getState type to RootState in createAsyncThunk

The createAsyncThunk can have the types defined on the generics:

export const unsubscribeMeta = createAsyncThunk<apiUnsubscribeResponse, void, {state: RootState }>(
  'meta/unsubscribe',
  async (_, { getState }) => {
    const { meta } = getState();
    const res = await client.post<apiUnsubscribeResponse>(
      `/meta/unsubscribe/${meta.subscriptionId}`
    );
    return res.data.data;
  }
);

Defining the state will automatically make the getState be aware of the application state.
