Terraform does not clean up prices added via CM

[dmacbride-ep]

Description

If I manually add additional currencies to a product-price that was created by Terraform, Terraform can detect the changes and says it will clean them up, but then silently does not.

Steps to Reproduce

• Using terraform: create a product, currency, and pricebook, then add a product-price for the product in that currency and pricebook
• log in CM, add a new currency to the store, then add a price for the product in that new currency, in the same pricebook as before
• go back to terraform and re-run terraform apply to fix the drift.

Expected Results

Terraform will detect the drift, identify changes to make, and make them. When you subsequently inspect EPCC you see the changes are in fact done.

Actual Results

Terraform detects the drift, identifies changes to make, and says it has made them. However, when you subsequently inspect EPCC you see the changes are NOT done.
