Unfortunately, it looks like that repository is too big. We allocate 3GB of space for /cloud/projects and the device ran out of space while it was trying to clone that repository.
Right now there isn't a way to configure more storage for a project, but that is something we are considering for a future release. In the meantime, you will need to remove some files from that project if you want to create a project from that url. Sorry about that.
thanks
