Multi in Uni combine

[uPagge]

Is it possible to cram Multi into Uni.combine().all() ?

When I try to somehow convert Multi to Uni and pass it to Uni.combine, I get this

Connection was closed: io.vertx.core.VertxException: Connection was closed

A Uni only emits once but you're feeding something that emits multiple events to it.
If you take one from the Multi by doing toUni(), it should work...

and what will I get by doing toUni? Random element from Multi? I need a collection of elements in order to do something with it. Uni<List<?>>

But when I do it on the receiving service side, converting Multi to Uni, I get this error. And if I do it on the side of the giving service, that is, I get Multi from the database, then I convert it to Uni and give it to another service, then everything works

you'll get the first element by doing toUni().
Multi means multiple emissions of an object.

Can you show some code? Not sure what you're trying to do....
