Error sprite-animation-clip.js upon restarting same scene

Hello :wave:

I checked same game in version 1.61.3 works fine.

But giving error in version 1.62.1 and 1.62.2 (current).

Upon calling restart scene game got stuck with following error.

Can you create a public repro project please for us to look at?

@yaustar Please check DM. As i can not share link in public.

I’ve had a quick look at the project and this issue has been fixed in this PR Add null check before unbinding events sprite animation clip by yaustar · Pull Request #5272 · playcanvas/engine · GitHub

The real issue is that the Entity ‘bubble’ in the gameplay scene still had a reference to the sprite_ballon_green asset that is excluded from the project.

The entity is set to be ‘animated’ but if you switch it back to type ‘simple’, you can see the asset is being referenced still

I’ve removed the reference in your project and switched it back to animated which has fixed the issue
