iOS combine Publishers.Just deprecated

In a operator chain like this you used to be able to return Publishers.Just(defaultValue) but it is deprecated and I can't find a way to do this functionality anymore. What is the new way to return a defaultValue?

 $query
    .throttle(for: 0.5, scheduler: DispatchQueue.main, latest: true)
    .removeDuplicates()
    .map { query -> AnyPublisher<[Repo], Never> in
       guard query.count >= 3 else {
          return Publishers.Just([])
                   .eraseToAnyPublisher()
          }
          return API().search(with: query)
               .retry(3)
               .eraseToAnyPublisher()
          }

I was able to get this to work: 

Result.Publisher([])
    .eraseToAnyPublisher()

If you need to send back just an error, you'll likely need to specify the type as well:

Result<YourObject, YourError>.Publisher(.failure(YourError.error))
    .eraseToAnyPublisher()
