terraform-provider-confluent: confluent_kafka_topic - Cannot import topic resource in a dedicated cluster

Hello,

I am having an issue importing topics when the cluster type is dedicated. The config block is an empty block in the state file after import.

terraform version: 1.3.6
Confluent Cloud Provider: 1.26.0

Example:

terraform {
  required_providers {
    confluent = {
      source  = "confluentinc/confluent"
      version = "1.26.0"
    }
  }
}

provider "confluent" {
  cloud_api_key    = "<api_key>"
  cloud_api_secret = "<api_secret>"
}

resource "confluent_kafka_cluster" "cluster" {
  display_name = "<cluster>"
  region       = "eastus2"
  availability = "SINGLE_ZONE"
  cloud        = "AZURE"
  environment {
    id = "<env_id>"
  }
  dedicated {
    cku = 1
  }
}

resource "confluent_kafka_topic" "topic" {
  kafka_cluster {
    id = confluent_kafka_cluster.cluster.id
  }
  topic_name       = "topic"
  partitions_count = 6
  rest_endpoint    = confluent_kafka_cluster.cluster.rest_endpoint
  config = {
    "cleanup.policy"                        = "delete"
    "confluent.key.schema.validation"       = "false"
    "confluent.key.subject.name.strategy"   = "io.confluent.kafka.serializers.subject.TopicNameStrategy"
    "confluent.value.schema.validation"     = "false"
    "confluent.value.subject.name.strategy" = "io.confluent.kafka.serializers.subject.TopicNameStrategy"
    "delete.retention.ms"                   = "86400000"
    "max.compaction.lag.ms"                 = "9223372036854775807"
    "max.message.bytes"                     = "2097164"
    "message.timestamp.difference.max.ms"   = "9223372036854775807"
    "message.timestamp.type"                = "CreateTime"
    "min.compaction.lag.ms"                 = "0"
    "min.insync.replicas"                   = "2"
    "retention.bytes"                       = "-1"
    "retention.ms"                          = "604800000"
    "segment.bytes"                         = "104857600"
    "segment.ms"                            = "604800000"
  }
  credentials {
    key    = "<cluster_api_key"
    secret = "<cluster_api_secret>"
  }
  lifecycle {
    prevent_destroy = true
  }
}

State File after import:

{
  "version": 4,
  "terraform_version": "1.3.6",
  "serial": 6,
  "lineage": "082cc1c7-2166-44ae-945f-95ea099240ab",
  "outputs": {},
  "resources": [
    {
      "mode": "managed",
      "type": "confluent_kafka_topic",
      "name": "topic",
      "provider": "provider[\"registry.terraform.io/confluentinc/confluent\"]",
      "instances": [
        {
          "schema_version": 2,
          "attributes": {

            "credentials": [
              {
                "key": "<cluster_api_key>",
                "secret": "<cluster_api_secret>"
              }
            ],
            "id": "<cluster_id>/<topic_name>",
            "kafka_cluster": [
              {
                "id": "<cluster_id>"
              }
            ],
            "partitions_count": 6,
            "rest_endpoint": "<cluster_rest_endpoint>",
            "topic_name": "topic"
          },
          "sensitive_attributes": [],
          "private": "<redacted>"
        }
      ]
    }
  ],
  "check_results": null
}

Importing topics on basic cluster works and the config block with default properties are imported successfully.

Thanks for your help.
