Error on Resume in Tabular Workflow View – ObjectNotExistError (UnknownKey: Position 1)

Current Behavior:

When resuming a suspended order for a stopped job from the Tabular Workflow view, and selecting a variable checkbox (for example, Return Code), the operation fails with the following error:

• ObjectNotExistError: UnknownKey: No such Position: 1

As a result, the order does not resume.
This issue occurs only in the Tabular Workflow view. Performing the same action in the Graphical Workflow view works correctly.

Steps to Reproduce:

• Create a workflow with three jobs.
• Go to the Workflows view.
• Stop the second job in the workflow.
• Add an order to the workflow.
• Wait until the order reaches the Suspended state.
• In the Tabular Workflow view, click Resume on the suspended order.
• Select a variable checkbox (for example, Return Code).
• Click Submit.

Desired Behavior:

When resuming a suspended order from the Tabular Workflow view, selecting variable checkboxes (such as Return Code) should resume the order successfully without any error.
