Hi,

I am attempting to register my new WH-1000XM3 headphones at https://www.sony.co.uk/mysony/product/register.

I have filled in the form, and the model name is recognised client-side.

But when I fill in serial number and purchase details, then submit…

I get this error "Product model is invalid":

These are the form params that it is POSTing (plus other params concerning purchase details and serial number, which I've redacted):

Category-1	GLOBAL
Category0	eu-all_audio-video
Category1	eu-all_audio-video-headphones
Category2	eu-all_headphones-wireless-headphones
Category3	eu-all_wireless-headphones-bluetooth-headphones
Category4	WH-1000XM3
country	GB
productModelName	WH-1000XM3

The submitted parameters all look correct.

This looks like a server-side bug.

How can I register my headphones?
