Hi all,
please I’d like to share this problem I have when I use this library on a Pre-request-script. It is important to highlight that this is not a problem of the script or request, because this same environment is used on other Windows x64 PC and it works OK, however when I use it on my laptop, for any reason, it fails.
I’ve tried updating postman to the last version, even using the web environment, but on this pc the problem keeps returning error.
var sToken = KJUR.jws.JWS.sign(header, Header, Payload, jwtKey);
Response error: 
There was an error in evaluating the Pre-request Script:ReferenceError: KJUR is not defined
This same request through my postman internet account on other pc using W10 runs OK. Of course I’ve not modified any configuration of the settings.
Thanks a lot for your help.
