DB Connector (Labs) not working from WebPortal

KNIME Server
1

Dear KNIME Team members,

I have created a simple workflow using the node DB Connector (Labs). This node is used to establish a connection with SAP HANA Enterprise. I am reading the data from an Excel file and inserting the same data in HANA Enterprise. Everything is working fine if I am using the workflow from local workspace. I have even pushed the workflow to KNIME Server and it is working fine.

The problem starts when I try to execute the workflow from WebPortal. I am receiving the following error message -
Status: DataLoadError: DB Connector 3:19
Status: DataLoadError: Loading model internals failed: Database driver could not be found: “HANA”

Can you provide any solution? Am I missing something on server?

P.S. I am using KNIME 3.7

Best regards
Piyush Bansal

Hi there @piyushbansal08,

welcome to KNIME Community!

Have you added the path to the driver to your preferences.epf file?

Hi piyushbansal08,
you can also find detailed information about the server setup in the database documentation.
