JSPException when managing user roles in WSO2 API Manager - wso2

Question

We are using WSO2 API manager version 1.10.0. We are getting errors on the WSO2 API manager console when trying to view user roles or modify user roles. I am getting this error when I am trying to view roles assigned to existing users, or when I am trying to assign new roles to existing users.
Errors seen are:
JSPException while including path '/role/view-users.jsp'
JSPException while including path '/user/edit-user-roles.jsp'
JSPException while including path '/user/view-roles.jsp'
etc..
