Hello,
It's just the line that encodes the workflow that I changed by telling it to
change all the '-' characters to a '+'
String data = "{\"document\":\"data:application/octet-stream;base64," +
Base64.encodeToString(sb.toString().getBytes("UTF-8"),
Base64.URL_SAFE|Base64.NO_WRAP).replace('-', '+') +"\"}";
Cheers,
Ian
