[Bug] `elasticstack_elasticsearch_snapshot_repository` gcs.base_path is ignored

[baprx]

Describe the bug

I want to configure the Base path of a GCS snapshot repository but the Terraform provider ignores the base_path setting. If I manually add it on the console, the plan doesn't even show the diff.

To Reproduce
Steps to reproduce the behavior:

1. TF configuration used

resource "elasticstack_elasticsearch_snapshot_repository" "gcs" {
  name = "elasticsearch-backup"

  gcs {
    bucket    = "elasticsearch-backup"
    base_path = "elasticsearch-data"
  }
}

2. TF operations to execute to get the error : terraform plan

Expected behavior
The base path setting should be updated.

Versions (please complete the following information):

• OS: MacOS
• Terraform Version 1.9.8
• Provider version v0.11.11
• Elasticsearch Version 7.17.0

I just realized the behavior is not exactly as described, here's what is happening :

Base path configured on Kibana	base_path set in Terraform	Kibana Base Path == Terraform base_path?	Terraform plan shows diff?	Expected behavior?
Yes	No	No (Terraform should set it to null or empty string)	No	No
Yes	Yes	Yes	No	Yes
Yes	Yes	No	Yes	Yes
No	No	Yes	No	Yes
No	Yes	No	Yes	Yes

If it's the normal behavior (base_path not set -> don't edit it on Kibana even if it is set), feel free to close the issues.

Thanks for the bug report, the table is especially helpful, 💯!

This is correct. The provider won't show a diff for unconfigured attributes in this case (any most optional attributes across the provider). Another test case worth checking prior to closing this is the behaviour when base_path = null in Terraform. This should reset the base path to the ES default but I wouldn't be surprised if that's not the current behaviour though. I'll leave this open until we get a chance to test that case out.

Thanks for clarifying 🙂 I just tested with null and it ignores the change as well, the plan shows No changes although there is a base path configured.
