Hello,

I have used a " **loop out**" expression in my animation, and when i tried to export it says " **unable to execute script at line 18. syntax error lottie**". When i view it on my mobile only the key frame part of it is getting animated and not the expression part of it. Is lottie supposed to not export AE expressions?

Thank you

@abhiraj.lucky1 You should be able to do that… at least from what I’ve done in the past I’ve been able to.

It’s also possible to convert expressions to keyframes, then export. It doesn’t always work with really complex expressions.

**In after effects:**

1. Select the Layer
2. press EE to show all expressions on that layer
3. select each property you want to convert
4. go to Animation \> Keyframe Assistant \> Convert Expressions to Keyframes

Can you send a screenshot of your code? You can also send me (email) the file and I can diagnose.
