Unable to transfer eSIM from iPhone 17 to replacement iPhone 17

Hi, I have been talking to support for over 2 hours but they have not been able to fix the issue. I have 2 iPhone 17s, one just got sent to me from apple, and I need the new one to have my eSIM. Everytime I go to scan an eSIM qr code it just says "eSIM cannot be added, this code is no longer valid." This has happened with multiple different codes, everytime I try to scan them. Was hoping someone knows what to do in this situation.
