Convert expressions to keyframes render failed

Hi,

Due to the use of CSP (Content security policy) we can’t use the lottie webplayer on our site. So we have to use the light player. But for some reason the animations we made using DUIK are not working anymore. On the webplayer they are working fine but on the light version they don’t. I wanted to export my animations using the setting “Convert expressions to keyframes” I think this might be the solution, but then it stops rendering half way and says Render failed.

What could I do to fix this?

Thanks,

Jesse Johnson
