_tkinter.TclError: wrong # args: should be "wm iconbitmap window ?bitmap?"

From what I read on stackoverflow , this might need an .xbm on Unix

Traceback (most recent call last):
  File "main.py", line 5, in <module>
    app = gui.main()
  File "postgres-gui/gui.py", line 20, in __init__
    tk.Tk.iconbitmap(self, default='./icons/now-black.ico')
  File "/usr/lib64/python3.8/tkinter/__init__.py", line 2069, in wm_iconbitmap
    return self.tk.call('wm', 'iconbitmap', self._w, '-default', default)
