Error with clang-format in ensure_installed

[AllergicMushroom]

I always get an error with clang-format if it is in ensure_installed, but I can install it manually and it works.

Here's my config:

return {
    'williamboman/mason.nvim',
    lazy = false,
    dependencies = {
        {
            'williamboman/mason-lspconfig.nvim',
        }
    },
    keys = {
        { "<leader>cm", "<cmd>Mason<cr>", desc = "Mason" },
    },
    config = function()
        require('mason').setup()
        require('mason-lspconfig').setup({
            ensure_installed = {
                -- C++
                'clangd',
                'clang-format',
                -- Lua
                'lua_ls',
                -- LaTeX
                'texlab',
                'ltex_plus',
            }
        })
    end
}

I get [mason-lspconfig.nvim] Server "clang-format" is not a valid entry in ensure_installed. Make sure to only provide lspconfig server names.

However, installation it from :Mason makes it work, even if the error message still appears. Am I missing something? I checked the registry and it seems to be the good name.
