ERROR Database Table Connector (legacy)

I have a flow that extracts data from the oracle database, it was used to work but now when I run it, I will face the below Error. I would be appreciated it if anyone could explain the root cause.
Execute failed: oracle/jdbc/driver/T4CCharAccessor$1


Thank you for contacting KNIME regarding this issue.

My understanding of the issue is that your workflow, which extracts data from an Oracle DB, was working but now does not, and produces an error message when executed.

If this is correct, please confirm and I will research the issue further for you.

Please provide the following additional information for troubleshooting:

  • Is this workflow running in AP or on a KNIME server?
  • If it is running on a KNIME server, What operating system is your KNIME server software running on?
  • What version of KNIME Server (KS)/KNIME Executor (KE) are being used?
  • What operating system is your KNIME client software running on?
  • What version of KNIME Analytics Platform (AP) is being used?
  • Does the issue affect only one user, multiple users, or all users?
  • Have there been any external changes to the environment that could explain the issue (e.g. configuration changes, AP upgrade, new extensions/patch applied, etc.)
  • Are you able to provide DEBUG logs for the time period covering this issue?

I look forward to helping you resolve this issue!
