Hello, the code I have right now while attempting to create a document type that includes Umbraco.MultiUrlPicker with some static data looks like this:

                ReadMoreLinks = new List<Link>
                {
                    new Link
                    {
                        Target = "_blank",
                        Name = "Test link",
                        Url = "https://google.com",
                        Type = LinkType.External,
                        Udi = Udi.Create(Constants.UdiEntityType.Document, Guid.NewGuid())
                    }
                },

I initially tried creating it without any sort of Udi/Guid, which successfully creates the link in the picker but throws an error while browsing the site. When I have the code as above it doesn't create it at all. I've tried a few different variations but I'm not sure how to go about this anymore. Thanks in advance
