Plugin Help Error And Disconnection When Summoning A Firework

Hello! I'm currently having an issue where every time I summon a firework I get disconnected and get this error, not sure if anyone knows what it means, but I can't quite figure it out. Here is a list of plugins in case anyone knows of one that may be interfering and causing the error.

Firework Command (this command works on Single Player just not on the server): /summon Fireworks_Rocket ~ ~ ~ {LifeTime:1,FireworksItem:{id:fireworks,Count:1,tag:{Fireworks:{Explosions:[{Type:0,Flicker:1,Trail:1,Colors:[16711680],FadeColors:[0]}]}}}}


Any ideas, please respond!
