Since last week on Tuesday morning, this error shows up in the POS UI, after choosing the (credit) card payment method:

TypeError: can't access property "payment_method", line is undefined

We're using an Ingenico terminal, connected to an IoT box. The payment transaction itself is successful, even after this error, but the sale is not being registered in Odoo (so no customer receipts and messing up sales totals and accountancy).

This has been working for 2 years, and now it doesn't. I reinstalled the payment terminal, updated the IoT box to the most recent version, but no success. I logged a ticket, it seems to be a known issue, and now I'm waiting for a solution.

Anyone has the same problem? Any known work-arounds?

TIA.
