Transactions-View in E-Mail Template throwing error while using action

Hey! We’re seeing a weird issue with one of our invoice email templates.

If we open the PDF preview and click Send, everything works and the email draft opens as expected. But if we’re on the Invoices screen (AR.30.10.00) and use the Email action, it fails every time with this error (Trace-Log):

Our template includes this block below. If i exclude it, the action works. This code seems to work for other customers in other instances, so I’m struggling to understand why it fails in this environment. Any ideas what could cause this difference? Do i miss something?

            <div data-foreach-view="Transactions" style="display: flex; justify-content: space-between; padding: 12px 20px; border-bottom: 1px solid rgb(241, 243, 244); align-items: center;">

            </div>

Thank you.
