NvDash: Mouse Invoked Invalid Cursor Position Causes Error

[ochi12]

How to reproduce this issue:

1. open nvdash
2. click anywhere from the nvdash buffer except for the item areas
3. navigate up and down
4. an error message should appear.

Error produced:

E5108: Lua: ...i12/.local/share/nvim/lazy/ui/lua/nvchad/nvdash/init.lua:214: Expected 2 arguments
stack traceback:                                                                                              
        [C]: in function 'nvim_win_set_cursor'

/lazy/ui/lua/nvchad/nvdash/init.lua:213> 

Why the above error appears:

 local key_movements = function(n, cmd)
    local curline = fn.line "."

    for i, v in ipairs(key_lines) do
      if v.i == curline then
        local x = key_lines[i + n] or key_lines[n == 1 and 1 or #key_lines]
        if cmd and x.cmd then
          vim.cmd(x.cmd)
        else
          return { x.i, x.col }
        end
      end
    end
  end

as you can see this function responsible for returning the new cursor position doesn't always return a valid line and col coordinates. Instead a return value only occurs inside the if v.i == curline scope . when v.i is not equal to curline ( in invalid cursor pos), it returns a nil and we see the error I pasted above.
