JSON Web Tokens error in new modeler

Hi, I'm using the JSONWeb Token module. In Mendix modeler 7.10 this module was/is working fine. I've upgraded Mendix to 7.11 and now the token gives the following error:  java.lang.NoSuchMethodError: org.apache.commons.codec.binary.Base64.encodeBase64URLSafeString([B)Ljava/lang/String; Does someone know how to fix this problem?   Edit I already tried to update / reinstall the module and some other modules. I also looked for duplicates in the userlib folder and deleted the duplicate ones. Both did not do anything unfortunately.  Thanks!

Hi Joris,

Did you really didn't do anything else, like updating a module? Most of the time, these problems with Java occur because of duplicate files or different versions of the same library. Maybe Mx 7.11 included a Apache Commons library themselves. Could you verify which lib-files you have in the userlib folder which have Apache and Commons in its name?  (like org.apache.commons.lang3.jar). Try to delete duplicates and then try again.

Hopefully this is the case!

Kind regards,
