Error when commands listed in EmptyView are unbound.

[gmardom]

When I disabled default bindings to assign my own from scratch, lite-xl stopped working.

Minimal Config

local keymap = require "core.keymap"

keymap.map = {}
keymap.reverse_map = {}

Potential solution

   y = y + (dh - (th + style.padding.y) * #lines) / 2
   local w = 0
   for _, line in ipairs(lines) do
-    local text = string.format(line.fmt, keymap.get_binding(line.cmd))
+    local text = string.format(line.fmt, keymap.get_binding(line.cmd) or "N/A")
     w = math.max(w, renderer.draw_text(style.font, text, x + style.padding.x, y, color))
     y = y + th + style.padding.y
   end
