I solved it! Was, as the compiler was saying, a type inference problem.

With the following code:

val networkDataSourceAdapter: RxNetworkDataSourceAdapter<out BeerListResponse<out List<Beer>>> = createNetworkDataSourceAdapter()
        val cachedDataSourceAdapter: CachedDataSourceAdapter<List<Beer>,Beer> = getBeerLocalSource()
        return FountainRx.createNetworkWithCacheSupportListing(
            networkDataSourceAdapter = networkDataSourceAdapter,
            cachedDataSourceAdapter = cachedDataSourceAdapter,
            firstPage = FountainConstants.DEFAULT_FIRST_PAGE,
            ioServiceScheduler = <http://Schedulers.io|Schedulers.io>(),
            ioDatabaseScheduler = <http://Schedulers.io|Schedulers.io>(),
            pagedListConfig = FountainConstants.DEFAULT_PAGED_LIST_CONFIG)
    }

Using the out kotlin keyword to explicit the types, the error message is finally gone.

Thanks anyway 🙂
