DBConnect: How to Edit DB Identies via REST API?

[PhuN]

I am using the REST API knowledge in -
https://community.splunk.com/t5/All-Apps-and-Add-ons/Splunk-DB-Connect-V3-How-create-Automated-Progr...

curl -k -u admin -X POST  https://va10plvspl344.wellpoint.com:8089/servicesNS/nobody/splunk_app_db_connect/db_connect/dbxproxy/identities/ID_NAME  -d "{\"name\":\"ID_NAME\",\"username\":\"myuser\",\"password\":\"mypwd\!123\",\"domain_name\":\"us\",\"use_win_auth\":true,\"port\":null}"

Enter host password for user 'admin':

{"code":500,"message":"There was an error processing your request. It has been logged (ID 7e7f61e0fdee4a8d)."}

This is the internal log msg:
