Multiple implementation issue in android studio 3.5

[minion06]

Overload resolution ambiguity all this function match

fun <T, R> LiveData.map(mapper: (T?) -> R?): LiveData = createMediator(this, MapExt<T, R>(mapper))
fun <T, R> SupportMediatorLiveData.map(mapper: (T) -> R): SupportMediatorLiveData = createMediator(this, MapExt<T, R>({
return@MapExt mapper(it!!)!!
}))

Shows error on using map extension function chaos in choosing map function .
