V6 - Translation fallback

[dimitriBouteille]

Describe the bug

Since the update of the module on v6, I have only problems ...

If I am not mistaken, on v5 there was a fallback system to use the parent locale if the local passed as argument of AdyenCheckout did not exist. Thus:

AdyenCheckout({
	locale: 'fr_CH',
})

The local fr_CH (fr_CA, ...) does not exist in Adyen so it was the local fr_FR that is loaded.

On v6, if I pass the locale fr_CH, it is the translations en_US that are loaded...

To Reproduce

Steps to reproduce the behavior:

1. Create card component with fr_CH or fr_CA locale
2. 💥 The component

Expected behavior

The parent locale must be loaded :

• fr_CH, fr_CA => fr_FR
• it_CH => it_CH
• de_AT, de_CH => de_DE
• ...
