Describe the issue

When a Subscription Item is added to the sales line (Sales Order or Quote), and corresponding Sales Subscription Lines are created, the user cannot open subscription lines directly by clicking the Subscription Lines field on the sales line.

Instead of showing the related subscription lines, the system displays the following error message:

Expected behavior

Clicking the Subscription Lines field on a sales line that includes a subscription item should open the related subscription lines page without an error message.

2. Add a Subscription Item with an assigned subscription package.
3. Click on the Subscription Lines field on the sales line.
4. The error message will be shown.

Actual result

The system throws an error, and the Subscription Lines page does not open.
