Data Store connection issues in the workbench

Hi ,

I am trying to connect oracle database using workbench. Connection test succeeded but I am getting the error like Cannot retrieve children nodes - browse remote error: Oracle <orcl> error message for operation <OCIStmtFetch>: <ORA-24338: statement handle not executed.

I have tried with designer, I can import table by table but I cannot browse all the metadata.

Please find the screenshots for reference
