terraform-provider-confluent: Provider crashes when creating confluent_schema resource

I use the following setup

schema.tf

resource "confluent_schema" "schema" {
  subject_name = "TestNamespace.TestSchema"
  schema = file("testschema.avsc")
  format = "AVRO"

  recreate_on_update = false
  hard_delete = false

  lifecycle {
    prevent_destroy = true
  }
}

setup.tf

terraform {
  required_version = "1.4.4"

  required_providers {
    confluent = {
      source  = "confluentinc/confluent"
      version = "1.42.0"
    }
  }
}

variable "schema_registry_api_key" {
  description = "Confluent Schema Registry API Key"
  type        = string
}

variable "schema_registry_api_secret" {
  description = "Confluent Schema Registry API Secret"
  type        = string
  sensitive   = true
}

variable "schema_registry_id" {
  description = "Confluent Cloud Schema Registry id"
  type        = string
}

variable "schema_registry_rest_endpoint" {
  description = "Confluent Cloud Schema Registry REST endpoint"
  type        = string
}

provider "confluent" {
  schema_registry_id            = var.schema_registry_id            # optionally use SCHEMA_REGISTRY_ID env var
  schema_registry_rest_endpoint = var.schema_registry_rest_endpoint # optionally use SCHEMA_REGISTRY_REST_ENDPOINT env var
  schema_registry_api_key       = var.schema_registry_api_key       # optionally use SCHEMA_REGISTRY_API_KEY env var
  schema_registry_api_secret    = var.schema_registry_api_secret    # optionally use SCHEMA_REGISTRY_API_SECRET env var
}

testschema.avsc

{
  "type": "record",
  "name": "TestSchema",
  "namespace": "TestNamespace",
  "fields": [
    {
      "name": "Id",
      "type": "string"
    },
    {
      "name": "Value",
      "type": "string"
    }
  ]
}

I set TF_VAR_… variables accordingly to set credentials to the schema registry cluster. when I run:

terraform init
terraform validate
terraform plan -out=tfplan
terraform apply tfplan

on the apply step the provider crashes with this message:

Error: The terraform-provider-confluent_1.42.0 plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.

Let me know if I can provide any additional information.
