I had same error. Then I changed the Kws to Palapa (Android-google play) is free. Put www folder inside pws/www. Then source folder is pws/www/www.
Open app, start web server. Its works for me ok.
I haven't played my Switch n a month or so, just been playing Xbox, and just picked to play lil and Damn that A and B, X and Y being reversed always gets me.
I agree Tears is great. I even played thru it completely twice. I've been hooked on playing thru Fallout 4 again though, after they released the next gen version for Series S/X. Is pretty cool update.
