vRack creation with Terraform as read/write contact

Hi,

I am trying to create a vRack from Terraform to be used with a Public Cloud project for which I am not the owner but have the "Read/Write" permissions. When applying my Terraform plan, I got an error saying that my POST call to `/order/cart/...` "has not been granted" despite my ability to create a vRack from the project dashboard.

Additionally, my OVH account is part of the Irish OVH subsidiary whereas the Public Cloud project I am trying to create a vRack for is part of the French subsidiary. Nonetheless, all my attempts to create a vRack failed, both with `ie` and `fr` as values of `ovh_subsidiary`in `ovh_order_cart`.

Have anyone even encountered such an issue?

Many thanks in advance.
