EPM Integration Agent throwing error on cred = agentAPI.getConnectionDetails()

Hi, we have a need to write back using EPM Integration. write back is working fine but before write back we need to clear data out of oracle tables. so we are trying to write custom SQL. For connection to the SQL we are using Agent API method to get the connection details in BefExport.py.

cred = agentAPI.getConnectionDetails()

However it does not recognize getConnectionDetails() and errors out. The JDBC connection is defined in the application that we set up for write back and the insert query is working fine. The delete is not working since we are not able to extract the JDBC connections and other details. we do not want to hardcode.
