neovim LuaSnip configuration problem, lua snippets work correctly, but json do not

I have an NvChad configuration for NeoVim, and I was trying to configure a LuaSnip plugin, but for some reason my Lua snippets are working correctly, but the json ones do not, and I want to figure out the reason for this

My cpp.json file is located at:

~/.config/nvim/snippets/vscode/cpp.json

My cpp.lua file is located at:

~/.config/nvim/snippets/lua/cpp.lua

Here is my configuration for LuaSnip:

return {
    "L3MON4D3/LuaSnip",
    dependencies = { 
        "rafamadriz/friendly-snippets", 
        "nvim-treesitter/nvim-treesitter", 
    },

    config = function()
        local ls = require("luasnip")
        local base = vim.fn.expand("~/.config/nvim/snippets/")
        
        require("luasnip.loaders.from_lua").load({ 
            paths = { base .. "lua" } 
        })

        -- require("luasnip.loaders.from_vscode").lazy_load()
        require("luasnip.loaders.from_vscode").lazy_load({ 
            paths = { base .. "vscode" } 
        })
        
        ls.config.set_config({
            keep_roots = true,
            link_roots = true,
            link_children = true,

            update_events = "TextChanged, TextChangedI",
            delete_check_events = "TextChanged",
        })
    end,
}

Here is the body of my cpp.json file:

{
    "simpleTest": {
        "prefix": "ttest",
        "body": ["123"]
    }
}
