Errors on empty center/footer sections

[Astrantia]

Describe the bug I only use the banner art for dashboard, and have no need for menu navigation

To Reproduce Setup ur config like

local db = require("dashboard")
db.setup({
    theme = 'doom',
    config = {
        header = {
            [[]],
            [[]],
            [[]],
            [[]],
            [[]],
            " SOME ASCII ART",
            version_lines[2],
        },
        center = {
            {
                icon = '',
                icon_hl = 'group',
                desc = '',
                desc_hl = 'group',
                key = 'c',
                key_hl = 'group',
                action = '',
            },
        },
        footer = {}
    }
})

Expected behavior No errors

The error is:

Error detected while processing UIEnter Autocommands for "*":
Error executing lua callback: ...re/nvim/lazy/dashboard-nvim/lua/dashboard/theme/doom.lua:111: attempt to perform arithmetic on local 'col' (a nil value)

Some if checks for the arithmetics would make it not error. I understand that many people don't use dashboard like me however.

[glepnir]

the latest version of dashboard?

[Astrantia]

the latest version of dashboard?

yup. this has been a problem since the big rewrite. with v1 it wasn't a problem

[glepnir]

this should work

 require("dashboard").setup {
        theme = 'doom',
        config = {
          header = opts.header,
          footer = { opts.footer },
          center = {
            {
              desc = '',
            },
          },
        }
      }

That errors for me with the same error:
