My Environment

I've created new storage account for the backend in another subscription, manually moved terraform state, but now terraspace can't access the storage account in another subscription.

Software	Version
Operating System	WSL ubuntu 22.04 x64
Terraform	1.4.0
Terraspace	2.2.15
Ruby	3.3.0

Expected Behaviour

Terraspace works with resources in one subscription, specified in ARM_SUBSCRIPTION_ID variable, and successfully stores the terraform state in the storage account of another subscription without errors.

Current Behavior

Terraspace doesn't care about subscription_id in backend config,
TS tries to find resource group in the wrong subscription and of cause can't find. Then TS creates new resource group in the wrong subscription. Then TS tries to create storage account(which already exists in another subscription). Then TS tries to create container in the storage account and fails with 404 Not Found error:
