The script loaded online working perfectly. The program will be used offline so i load the dymo sdk script offline. i copied/paste the response to the request
https://s3.amazonaws.com/download.dymo.com/dymo/Software/JavaScript/dymo.connect.framework.js
in a file called dymo.connect.framework.js in the main folder
when i load the script from <script src="dymo.connect.framework.js"></script> in the main html file, i get a error Uncaught SyntaxError: invalid range in character class to the line goog.i18n.bidi.rtlCharReg_ = new RegExp('[' + goog.i18n.bidi.rtlChars_ + ']'),
i don't understand why the error appear only offline.
