Getting NPE in 6.0.0 version at com.airbnb.lottie.model.layer.SolidLayer.drawLayer(SolidLayer.java:43)

Hi @gpeal @bodymovin, I am getting NPE in 6.0.0 version also. Upgraded Lottie version in my Android app from 4.1.0 for the same issue. Checked it on Android 10 and 12. What shall I do?

I got it working by changing my animation json file.

[brookmg]

@sandeepyohans Can you tell us what your changed and the example animation json?

[sandeepyohans]

Hi @brookmg The exception was introduced after removing two layers from animation using Adobe AE. I opened my animation file (which was working fine) in online lottie editor. I removed the layers which I did not want and exported it in dotLottie format. This worked for me.

My animation file has more that 70k lines so won't be able to create a sample json here.

[brookmg]

Alright, thanks. Can you perhaps share the layers you removed from the file? It might help debug what's causing the issue.

Going to close this since this animation was manually modified and it's possible that you produced an invalid animation as a result.
