Out of a sudden, all users were not able to access Timesheet module with error:
"com.ca.ppm.rest.exception.APISystemException: java.lang.NullPointerException: Cannot invoke "java.util.Map.get(Object)" because "defCol" is null"
STEPS TO REPRODUCE:
1. Use Clarity MUX as usual for timesheets for many users
Expected Results: All users to be able to access and submit Timesheets in MUX
Actual Results: Error on Page: "com.ca.ppm.rest.exception.APISystemException: java.lang.NullPointerException: Cannot invoke "java.util.Map.get(Object)" because "defCol" is null"
