Terraform Version and Provider Version

Terraform v1.7.5
on darwin_amd64
+ provider registry.terraform.io/oracle/oci v5.35.0

Affected Resource(s)

oci_sch_service_connector

Terraform Configuration Files

resource "oci_sch_service_connector" "test_connector" {
  compartment_id    = "ocid1.compartment.oc1..aaaamycompartment123456789abcdefghijklmnop"
  display_name      = "test-connector"
  description       = "test connector"
  source {
    kind = "logging"
    log_sources {
      compartment_id = "ocid1.compartment.oc1..aaaamycompartment123456789abcdefghijklmnop"
      log_group_id   = "_Audit"
    }
  }
  target {
    kind        = "functions"
    function_id = "ocid1.fnfunc.oc1.region.aaaamyfunction123456789abcdefghijklmnop"
  }
}

Expected Behavior

terraform apply should only add the required attributes to the resource state.

Actual Behavior

After terraform apply of the above code, undefined optional resource attributes like batch_rollover_size_in_mbs, batch_rollover_time_in_ms, batch_size_in_kbs, batch_size_in_num, batch_time_in_sec, etc. get added to the terraform resource state.

# oci_sch_service_connector.test_connector:
resource "oci_sch_service_connector" "test_connector" {
    compartment_id = "ocid1.compartment.oc1..aaaamycompartment123456789abcdefghijklmnop"
    defined_tags   = {
        "Oracle-Tags.CreatedBy" = "default/abc@xyz.com"
        "Oracle-Tags.CreatedOn" = "2024-04-02T17:00:00.000Z"
    }
    description    = "test-connector"
    display_name   = "test-connector"
    freeform_tags  = {}
    id             = "ocid1.serviceconnector.oc1.region.aaaamyconnector123456789abcdefghijklmnop"
    state          = "ACTIVE"
    system_tags    = {}
    time_created   = "2024-04-02T17:00:00.000 +0000 UTC"
    time_updated   = "2024-04-02T17:00:00.000 +0000 UTC"

    source {
        kind = "logging"

        log_sources {
            compartment_id = "ocid1.compartment.oc1..aaaamycompartment123456789abcdefghijklmnop"
            log_group_id   = "_Audit"
        }
    }

    target {
        batch_rollover_size_in_mbs = 0
        batch_rollover_time_in_ms  = 0
        batch_size_in_kbs          = 0
        batch_size_in_num          = 0
        batch_time_in_sec          = 0
        enable_formatted_messaging = false
        function_id                = "ocid1.fnfunc.oc1.region.aaaamyfunction123456789abcdefghijklmnop"
        kind                       = "functions"
    }
}

When trying to terraform apply new changes to the resource, it fails with the following error since batch_size_in_kbs and batch_time_in_sec are set to 0 which were not defined in the initial resource.

Setting the batch parameters would enable batching, however, we do not want batching to be enabled

Steps to Reproduce

1. terraform apply the above terraform configuration file (update the OCIDs)
2. make updates to the configuration file. For example, update the description.
3. terraform apply the updated configuration file.
