Hey, I was wondering how subscribeScoped works (I am used to the Singles having onError/Success) and how to handle errors in my usecase? I am currently making a request to the backend and it returns the status and data, ktor suspend request so I wrap it in singleFromCoroutine. Am I supposed to wrap the call in try catch? Eg

return singleFromCoroutine {
            try {     
 val response: HttpResponse =
               <http://client.post|client.post>("${serverUrl}${apiEndpoint}/account")
 
                return@singleFromCoroutine CreateAccountResponse(response.status.value)
            } catch (e: Exception) {
                return@singleFromCoroutine CreateAccountResponse(500, e.message ?: "")
            }

I feel like I am seriously missing something here, I can't properly handle errors as I have to have a half-assed response network model that has to hold both the data and the potential error. Or is this the way to go?

Hello! subscribeScoped comes from Reaktive, it is described in the readme: https://github.com/badoo/Reaktive#subscription-management-with-disposablescope

You should be able to pass onError callback:

xxx.subscribeScoped(onSuccess = {}, onError = {})
