I am using import csv to database, where I need to pass the datasource name, but we have connected system datasource and when I am passing connected system datasource name it is giving me an error "Error: java.lang.reflect.UndeclaredThrowableException

Hello ashishdave 
There's a high chance that, Import csv to database smart service likely expects a traditional database connection, which connected systems might not provide.

Thank for Shubham,

Yes, I did try with several options but it is still giving me the same error with the connected system database, after that I tried to import the data into another schema in Maria DB using the traditional datasource like 'jdbc/Appian' and it works but in case of connected system it is giving me the same error 

Looks like Import CSV to Database smart service might not work with connected system data sources.
Plugin documentation doesn't have enough info. Still you can go through it.
