[Ellucian Mobile] Uknown error for registration-register

Database Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production PL/SQL Release 11.2.0.4.0 - Production

grails Grails 2.4.3.

Problem Whenever one of our Devs compiles and installs a modification or a new PLSQL report the Grails application stops working and only reponds with

"Uknown error for registration-register"

Solution for us was: make sure studentAPI Installed on the Database Server matches the StudentAPI war file on the Ellucian Mobile server

mongodb authentication failed code 18

If you are receiving this error and are 100% sure you are using the correct DATABASE username/password. try to update your mongodb client

PHP
pecl upgrade mongodb

Grails
add to to the BuildConfig.groovy file

compile "org.grails.plugins:mongodb:5.0.0.RC1"

Also if you are having problems serializing a list in Grails and only receiving the first item. It may be because <Domain Class>.list() does not return a list or array item but a MongoDB collection now (since MongoDB updates) to remedy this for now I have cast the lists to Arrays.
