We need to a add the academic session to Sakai LTI launches to help external Rubric tools.
Here’s the code to get the academic term in Sakai to pass via LTI
Site site = siteService.getSite(siteId);
String academicSessionId = site.getProperties().getProperty(termPropertyName);
if ((academicSessionId == "") || (academicSessionId == null))
