Hi!
first of all: help for nodeschool workshoper can be found here
https://github.com/nodeschool/discussions/issues
secondly: your filename is wrong, as forest said, there is no trailing
slash on __dirname. either you add it mnanually or use path.join()
thirdly: you can't do res.end(err). res.end() uses re.write() and write
expects a Buffer or a string. so if you want to present the error message
to the client you have to call res.end('"ERROR:" + err.message) or
something like that.
