Error while trying to trigger custom animation for Eco Pet.

[ThirdTecPatron]

Describe the bug
Effect "play_animation" doesn't work for eco pets with custom modelengine model. The model itself loads correctly, but I can't play custom animations using play_animation effect with triggers like jump, move etc. Console says that libreforge could not pass event.

To Reproduce

1. In your pet.yml file, under effects section, add play_animation effect.
   For example:

effects:
  - id: play_animation
    args:
      animation: attack
    triggers:
      - jump

2. On server, activate your pet
3. Trigger effect with your action (as jumping with the example above)
4. See the error in console.

Expected behavior
Selected pet plays specified animation with specified triggers

Server Information (please complete the following information):

• Server Version: 1.21.1
• Version of eco: v2.71.2
• Version of ModelEngine (premium): 4.0.8

Additional context
Bug persists with ModelEngine 4.0.7. Unofficial addon "MythicLibreForge" does not solve the problem. Server version 1.21.3 doesn't solve the problem either.
The error:
[23:20:39] [Server thread/ERROR]: Could not pass event PlayerJumpEvent to libreforge v4.72.2
java.lang.ExceptionInInitializerError: null
