It would be ideal if you could test if this problem persists when no other mod is installed.
If not, please narrow down the mod(s) that are causing the problem.

Which items did you have in your inventory when you died?
Can you send me your death file, thats located in your deaths directory of your world?

I'm playing on a multiplayer server and I'm not the owner.
The thing is, I went into the world border cause I didn't know it can kill you and died there, now I can't open my corps. And even the owner tried using the /death history command but he got the same result as me (getting kicked out with the same error code)

I can't help you without the death file.
