When trying to open a window to Twitch.tv from within the CodePen editor, I receive this error:
player.js:14 Failed to load ‘’ as a plugin, because the frame into which the plugin is loading is sandboxed.
How did I get around this? I didn’t change anything to my code, but I did switch to ‘Debug Mode’ on CodePen, clicked to open a window, and have had success every time.
I’m not sure why this works, but I’m hoping for an explanation!
