CLOB POST gives 500 on Fail-If-Exists

[krowvin]

Issue

When writing data to the CLOB endpoint via POST I attempted to test the "fail-if-exists" default functionality and got this error:

{"message":"System Error","incidentIdentifier":"-9047233463565875205","details":{}}

In the logs I see the correct DB error:
ORA-20020: ITEM_ALREADY_EXISTS

Expected

This error to be passed through to the enduser with something like:

{"message":"CLOB Exists"}

With an http status code of 409

Curl used on the request:

curl -X 'POST' \
  'https://t7-tomcat:port/swt-data/clobs' \
  -H 'accept: */*' \
  -H 'Content-Type: application/json;version=2' \
  -d '{
  "office-id": "SWT",
  "id": "myid.txt",
  "description": "my desc",
  "value": "Some Data"
  }'
