Debug output

Expected behavior

We had a previously deployed instance of Redis using IBM Cloud Projects.

We updated the disk size of the Redis instance in the config and selected Validate.

The disk size of the redis instance should be updated. None of the other resources managed by this config should be updated or replaced.

Actual behavior

You can see in the logs that the plan is to replace two secrets that were created as part of the Redis instance:

# module.secrets_manager_service_credentials[0].module.secrets["cm_redis_v72_jp_osa_prod_admin_pw"].ibm_sm_arbitrary_secret.arbitrary_secret[0] must be replaced
 2025/06/25 14:16:01 Terraform plan | -/+ resource "ibm_sm_arbitrary_secret" "arbitrary_secret" {

# module.secrets_manager_service_credentials[0].module.secrets["gc--cm-redis-v72-jp-osa-dn-prod"].ibm_sm_service_credentials_secret.service_credentials_secret[0] must be replaced
 2025/06/25 14:16:01 Terraform plan | -/+ resource "ibm_sm_service_credentials_secret" "service_credentials_secret" {

My assumption is that the ibm_sm_service_credentials_secret wants to be replaced because it was rotated since the config was created:

Terraform detected the following changes made outside of Terraform since the
 2025/06/25 14:16:01 Terraform plan | last "terraform apply" which may have affected this plan:

I'm not sure why it wants to replace the admin_pw

Steps to reproduce (including links and screen captures)

1. Run terraform apply
