Unable to load Prezi contents although its ID is valid.

[Kim Hyeongcheol]

Hello, I am working on a simple player for showing a Prezi content.

As given instructions and examples, I have completed setting up internal server and succeeded to see example Prezi contents and how links works.

However, when I tried to load my one, I can only see black canvas.

I enabled the debug option, and checked it out that the ID works  (attached its screenshot herewith). Is there anyone who can help me out this issue?

My Prezi ID : nso-wu3ui39p

(I tested the ID at the embedded code generator section of GitHub page and the same thing  happened. )

Thank you for your help in advance!
