Add List to MutableLiveData

I have a MutableLiveData and I want to add a List inside, but seems the below code doesn't work:

    private var factsLive: MutableLiveData<List<Fact>>? = null

private fun getObserver(): SingleObserver<List<Fact>> {
    return object : SingleObserver<List<Fact>> {
        override fun onSuccess(t: List<Fact>) {
            Log.d("test", "Succes")
            factsLive?.value = t
        }

        override fun onSubscribe(d: Disposable) {
            Log.d("test", "Subscribe")
        }

        override fun onError(e: Throwable) {
            Log.d("test", "Error")
        }
    }
}

This returns me MutableLiveData like null.

Make your variable like this:

private var factsLive: MutableLiveData<List<Fact>> = MutableLiveData<>()
