Is it possible to install a CoroutineExceptionHandler in a viewModelScope when e.g. initialising an Android ViewModel ? I want that exceptions by every Coroutine that are then started in this scope are then handled by the handler.

Can’t set it on an existing scope, you’d create a new scope out of viewModelScope + CoroutineExceptionHandler { }

Can’t find the reference on viewModelScope anywhere, is that overridable?

Ive got something like this:

abstract class BaseViewModel : ViewModel() {

    private val mapperExceptionHandler = CoroutineExceptionHandler { _, throwable ->
        setErrorFromMapperPresentation(throwable.message)
    }

    val presentationMapperContext : CoroutineContext = <http://Dispatchers.IO|Dispatchers.IO> + mapperExceptionHandler

And use it like this:
private val _ranking = MutableLiveData<SellRanking>()
val ranking : LiveData<RankingModel> = _ranking.switchMap {
liveData(presentationMapperContext) {
emit(mapper.rankingDomainToPresentation(it))
}
}
