run_config.lua:54: attempt to index global 'buf' (a nil value)

[rwkiii]

I have a PANIC error I when running ESPBootloader. What is the proper way of fixing this?

Serial output displays over and over as init.lua is restarted.:

Seems like the html file was in wrong location. Changingif (file.open('html/configform.html','r')) then to your html file location, solved this error.
