Backpack does not drop on deathSolved

I don't know where we tested before the wipe, the backpack was dropped when someone died. Now after the wipe, I try to get it working again all the time, only to no avail.
:/

  "Drop on Death (true/false)": true,
  "Erase on Death (true/false)": false,

    }
  },

Have you granted the backpacks.keepondeath permission by chance?
