# google_storage_bucket_object.gsn-psc-informations must be replaced
-/+ resource "google_storage_bucket_object" "test" {
      ~ content          = (sensitive value) # forces replacement
      ~ content_type     = "text/plain; charset=utf-8" -> (known after apply)
      ~ crc32c           = "+Yfdfw==" -> (known after apply)
      ~ detect_md5hash   = "4zoxBKTWpq0ORYqR4FRpCg==" -> "different hash" # forces replacement
      - event_based_hold = false -> null

      - metadata         = {} -> null

storage: The update on `google_storage_bucket_object` content is now no more delete to create object, but just push a new object if the content change

While using this provider version, its failing with below -

│ Error: Provider produced inconsistent final plan
│
│ When expanding the plan for google_storage_bucket_object.kubeconfig to
│ include new values learned so far during apply, provider
│ "registry.terraform.io/hashicorp/google" produced an invalid new value for
│ .detect_md5hash: was cty.StringVal("different hash"), but now
│ cty.StringVal("ZndE4b6y617AZSEAQdDH8w==").
│
│ This is a bug in the provider, which should be reported in the provider's
│ own issue tracker.
