[Bug]: Terraform does not recognize a diff in parameters following a failure of an SC provisioned product update. Subsequent TF Apply runs do not re-update the provisioned products

[MohammedJennane]

Terraform Core Version

1.7.5

AWS Provider Version

5.5.0

Affected Resource(s)

aws_servicecatalog_provisioned_product

Expected Behavior

• TF compares actual SC parameters with input parameters (P comparison with P')
• TF resends all SC input parameters on updates (which seems to be the way SC works on the console)

Actual Behavior

Terraform does not recognize a diff in parameters following a failure of an SC provisioned product update. Subsequent TF Apply runs with same parameters do not re-update the provisioned products.

Assume you have a provisioned product that was successfully provisioned with parameter values P={p1,..,pn} and you are trying to update with a set of Parameter values P'={p'1, .. p'1n}. Let's also assume TF triggers the update of the SC product and that this update failed for an arbitrary reason.

This results in the following:

• SC parameters in TF state = P' (updated)
• But Actual SC parameters = P
• Subsequent TF updates with P' do not run (Terraform see no change). Forcing us to change P' (often times with undesired side effects)

No changes. Your infrastructure matches the configuration.

Terraform has compared your real infrastructure against your configuration
and found no differences, so no changes are needed.

Steps to Reproduce

• Provision an SC product (successfully) with a set of a parameter values P={p1, ..., pn}.
• Attempt an update by changing a subset of parameter values P'={p'1, ..., p'm} (n>=m) in such a way that results in an error on the product.
• Wait for product to roll back then attempt another update with P'
• TF Apply does not run as no diff is seen by TF
