Unterminated character class

[redrockzee]

This is my file server startup.
:
var jsDAV = require("jsDAV");
jsDAV.debugMode = true;
var jsDAV_Locks_Backend_FS = require("jsDAV/lib/DAV/plugins/locks/fs");

jsDAV.createServer({
node: "./webdav",
locksBackend: jsDAV_Locks_Backend_FS.new("./webdav")
}, 8889);

I get this error when performing a GET on a docx file on Windows. Is the Windows path the problem?

This code throws the error:
/**

• returns 1: '    Kevin van Zonneveld'

  exports.rtrim = function(str, charlist) {
  charlist = !charlist ? " \s\u00A0" : (charlist+"").replace(/([.?/_{}+$^:])/g, "$1");
  var re = new RegExp("[" + charlist + "]+$", "g");
  return (str+"").replace(re, "");
  };

I fixed this by replacing this function so that it trims both / and \ rather than just using Path.sep. Path.sep contains \ on Windows and is not escaped properly for regular expressions in rtrim().

In tree.js:
getRealPath: function(publicPath) {
//return Path.join(Util.rtrim(this.basePath, Path.sep), Util.trim(publicPath, Path.sep));
return Path.join(Util.rtrim(this.basePath, '/\'), Util.trim(publicPath, '/\'));
},
