Investigate failed response object not sending correct 500

[jcadam14]

When testing new fi3 data inserted into the database manually, an incorrect value of -1 instead of NULL was put into the FI table for tax_id and rssd_id. This caused the object to be sent back from endpoints to fail data validation. The response to the client didn't have the message, it was a server 500 that also ended up getting wrapped in a CORS error.
