Did you try the number zero rather than the letter Oh?

Hello! How's everything?
I encountered strange error when running simple *.js file
setting a pin to output using beaglebone black Rev C which I received
this August.
I even reinstalled bonescript using
"npm install -g bonescript"
but still encounter the same error message.
led = "P9_11", "9_12" worked
led = "P8_39", "P8_40", "P8_41", and many other pins
do not work with error message listed below
following "simpleDigitalOut.js":
//====================================
//simpleDigitalOut.js
var b = require('/usr/local/lib/node_modules/bonescript');
var led = "P8_41";
b.pinMode(led, b.OUTPUT);
console.log("end of program");
