Adding Twitch video embeds

Hi everyone!

I'm currently working with a client who is on Twitch and would like me to add some of their previous streams and past stream playlists as videos on their site. I assumed grabbing the embed code and pasting it in a code block would be the way to go but I've ran into some issues and I'm not sure where they're stemming from. 

The Twitch embed seems to somewhat work but pops up with a dialogue box that says "Whoops! This embed is misconfigured. (Developers: please check your browser console for more information)" -- screenshot attached. I am not really certain where to go from here as I'm not super familiar with Twitch. Any suggestions would be much appreciated! 

Here is the video in question: https://www.twitch.tv/videos/737131486

Can you share link to page where you inserted twitch? We can check easier.
