Propagating 404 return codes

[bibble235]

I am using retrofit2 with RxJava. I am using a clean architecture, Presentation, Domain. I a developing a RESTAPI and want to manage the situation where the database is new and the tables are empty (404)

Here is my API

interface UserApi {
    @GET("users")
    fun getUsers(): Single<List<UsersDTO>>
 ...
 }

And here is part of my factory

    @RequiresPermission(value = Manifest.permission.INTERNET)
    fun getRetrofit(
        context: Context,
        gson: Gson,
        okHttpClientFactory: OkHttpClientFactory
    ): Retrofit =
        Retrofit.Builder()
            .addCallAdapterFactory(RxJava3CallAdapterFactory.create())
            .addConverterFactory(GsonConverterFactory.create(gson))
            .baseUrl(getBaseUrl(context))
            .client(okHttpClientFactory.createOkHttpClient(context))
            .build()

And I use this to pass to may repository

retrofit.create(UsersApi::class.java),
In the Presentation layer I receive the 404 retrofit2.adapter.rxjava3.HttpException as expected. However I do not want to import retrofit in the presentation layer but manage it in the data layer. Thoughts are to generate a custom exception shared between data and presentation or swallow the 404 in the data layer as no data is acceptable.

Thanks all.
