When attempting to perform Patch operation across data trees, the following response is currently returned

{    
"status": "500 INTERNAL_SERVER_ERROR",    
"message": "could not execute statement; SQL [n/a]; nested exception is org.hibernate.exception.DataException: could not execute statement",    
"details": "Check logs for details."
} 

This does not give much information regarding the actual issue and needs to be more specific.

• Return a 400 response code
• Along with this a descriptive message should be returned as well

Resolution:
