Single.concatDelayArray and .firstOrError() operator

Question

I have a case in my app where I want to fetch from multiple sources and return first valid data. I'd think .concatDelayArray() and .first() would be valid choices for this, but using them causes a crash if any of the non-last Singles throw an error.

Here's my test case:

Single<String> first = Single.fromCallable(() -> {
    throw new Exception("Random exception");
});
Single<String> second = Single.fromCallable(() -> "");
Single<String> third = Single.fromCallable(() -> "value");

Single.concatArrayDelayError(first, second, third)
    .filter(value -> !value.isEmpty())
    .firstOrError()
    .test()
    .assertValue("value");      

This ends with a crash:

io.reactivex.rxjava3.exceptions.UndeliverableException: The exception could not be delivered to the consumer because it has already canceled/disposed the flow or the exception has nowhere to go to begin with.

Is there a better operator for this case?
