Custom REST connector with Terraform

[Rafcio1987]

Hello
I am trying to create REST API connector throu terraform. On UI it works like a charm with connector builder but when trying to create the same using terraform i am getting :
unknown status code returned: Status 422 {"status":422,"type":"https://reference.airbyte.com/reference/errors#unprocessable-entity","title":"unprocessable-entity","detail":"The body of the request was notunderstood","documentationUrl":null,"data":null}
This is my config.What i am missing ? :

resource "airbyte_source_custom" "json_placeholder" {
  name         = "Custom JSONPlaceholder Source"
  workspace_id = var.airbyte_workspace_id  # Your Airbyte workspace ID
  configuration = jsonencode({
    url = "https://jsonplaceholder.typicode.com/",  
    http_method = "GET", 
    path = "/posts",  
    headers = {
      "User-Agent" = "python-requests/2.32.3",  # Example header
      "Accept"     = "*/*"                      # Example header
    },
    body = jsonencode({}),  # No body for GET requests
    primary_key = ["id"],  
    pagination_type = "None"
  })
}
