Razer Chroma SDK REST seems stuck

Hi guys,
I was trying to create a google chrome extension that colour the keyboard with the meta theme-color inside websites.
I was using razer chroma SDK rest because it is the only razer chroma SDK that is compatible with JavaScript.
But when I send the first post request to http://localhost:54235/razer/chromasdk the current animation in the keyboard became blocked and all the other static colors that I send to the new URI sent by the last request (http://localhost:sessionid/chromasdk/keyboard) don't work. It remains blocked until the new URI is alive. When it died it started again the default animation.

I don't know why it is doing this. Any suggestions?

Thank you.
