"Cannot read property 'uuid' of undefined" - GraphGist

Hi there everyone! I'm trying to upload my own graph gist, and everything works just fine, in the preview, the displayed content is fine. But when I try to continue with the process of uploading the graphgist, I press " save and continue" and end up getting the error of this post's title. "Cannot read property 'uuid' of undefined" .

Is it because the webpage is failing? What can I do to solve it? I've tried to found the solution but it seems no one has ever had it before.

The portal I used to upload it was: GraphGist Portal

Oh, nevermind, I already solved it. Looks like I needed to be registered in order to continue with the process.... :smiley:
