Panache Reactive - How to persist multiple entities?

[studioitc]

Hello,
which is the best way to persist a list of entities within Panache.withTransaction?
I'm trying to persist a list of string coming from a file.

List<Uni<MyEntity>> list = new ArrayList<>();
try (BufferedReader br = new BufferedReader(new FileReader(filePath))) {
String line;
  while ((line = br.readLine()) != null) {
     list.add(new MyEntity(null, line).persist());
   }
}

Now i suppose i need to combine somehow the list, i've tried with

Uni.combine().all().unis(list).combinedWith(v -> null).onItem()

but nothing is stored on DB.

Any suggestions?

Panache.withTransaction(() ->
        Uni.combine().all().unis(
                    session.persistAll(entityAList().toArray()),
                    session.persistAll(entityBList().toArray())
         ).asTuple().chain(unused -> Uni.createFrom().voidItem())
)

worked for me
