Error when using ExecuteSQL processor to DBCPConnectionPool

[#1]

Hi everyone,

I would like to ask for technical support in Apache NiFi 2.2.0. In my project, I want to integrate Apache NiFi 2.2.0 to Postgres, which is my data source using DBCPConnectionPool. I use ExecuteSQL processor to interact with PostgreSQL, but I encounter the following error when verifying.

Some solutions suggest me to check if DBCPConnectionPool is enabled or not. I go to check, it is already enabled.

Please help me.

Thank you in advance.
