Hey, guys, I getting a fatal null error from this .wpn file. Can anyone spot it?

It's been heavily edited, I'm trying to put everything into a sensible order and cut out as much useless text as I can but I probably cut out to much.

Spoiler

{
   "id":"zica_laser",
   "specClass":"projectile",
   "projectileSpecId":"zica_laser_shot.png",
   "type":"ENERGY",
   "size":"LARGE",
   
   "turretSprite":"graphics/weapons/zica_laser.png",
   "hardpointSprite":"graphics/weapons/zica_laser.png",
   
   "turretOffsets":[12, 0],
   "turretAngleOffsets":[0],
   "hardpointOffsets":[17, 0],
   "hardpointAngleOffsets":[0],
   
   "barrelMode":"ALTERNATING",
   "interruptibleBurst":false,
   "autocharge":true,

Well, is the name of the .wpn file the same as the weapon ID in the first line?  That can be a problem.
There's also the animation type.  I've never seen a vanilla weapon without an animation, despite there being "NONE" there, so that can be a problem too.

The projectilespecid, which points to the projectile file has a .png extension. This should point to the weapon's projectile file.

Ok, I replace projectileSpecId and textures with my own and this code work perfect, however if I make wrong projectileSpecId, game falls to null exception error, that could be the case

I never face with this problem using wpn files with names differ from their ID's

Excellent, that was indeed the problem, thanks everyone.
