# Paradigm Error - 404: Not Found, resource does not exist

**404: Not Found, resource does not exist \[unit-enrolments/XXXXXXXXX]**

***

This is a Paradigm error that occurs when a unit enrolment has been marked as deleted in TCSI but the UID field on the unit enrolment has not been reset.

To fix this error, just save the record again. When the 404 error occurs, the system clears the UID on the record. This allows you to submit the record again to TCSI.
