Checkout Translation through TranslationResources and TranslationRegister GraphQL

Hello,

Hope you all had a good day!!

I want to ask something related to translations. I want change the translation inside checkout page through shopify api with GraphQL using function TranslationResources and TranslationRegister

I manage to get the checkout translations list using TranslationResources with its locale, value, key, and digest.

But when I try to update with updated value (eg: “shopify.checkout.contact.address1_label”) inside TranslationRegister GraphQL, it said that “locale is invalid”, the response is something like below

The payload format that I tried was

Its kind of weird, because I get the key, locale, and digest from TranslationResources something like this

It’s “en” locale which is active by default.

Am I missing something? Why the error is “locale is invalid” when “en” locale was retrieved from TranslationResources?

Thank you
