you need to include the punctuation, specifically the ":"s, which usually are a "-", mac addresses use the ":" but unless the syntax has changed/broadened you have to have the "-" for seperating the fields in a uuid. The punctuation is part of the syntax (besides breaking the uuid into sections which makes it easier to copy/verify). for data overload see <https://en.wikipedia.org/wiki/Universally_unique_identifier> and the associated links.
