App Variant Creation: Needs Validation on Parameter Values

The customer reports that the "Lookback Days" field within the Assortment Advisor App's settings allows non-numeric or empty values. The "Run" and "Save" buttons remain active, enabling users to proceed with invalid input. When a variant is executed under these conditions, it results in a QueryStatus.FAILED_WITH_ERROR with the message: "001003: 1003: SQL compilation error: syntax error line 1 at position 77 unexpected ','".
