tvg_load_data Panics with Segmentation Fault When Loading Empty Lottie

[theashraf]

I'm encountering an issue when trying to load an empty Lottie file in the dotLottie-rs player. The function tvg_load_data is panicking and resulting in a segmentation fault error.

Here is the empty Lottie:

{
  "nm": "Untitled file",
  "ddd": 0,
  "h": 500,
  "w": 500,
  "meta": { "g": "@lottiefiles/creator 1.12.0" },
  "layers": [],
  "v": "5.7.0",
  "fr": 30,
  "op": 150,
  "ip": 0,
  "assets": []
}
