We customise some of the JavaScript in JasperServer following the instructions https://community.jaspersoft.com/documentation/jasperreports-server/tibco-jasperreports-server-ultimate-guide/vv900/js-ultimate-guide-_-customizing-_-customizing-javascript/ and in the build source, but the versions of NodeJS and Yarn required are very out of date and are causing problems with IT governance due to vulnerabilities in such old versions. Please upgrade the build scripts to allow support for up-to-date versions.
