Creating A DNS record with PHP (laravel)

Developers API
#1

Hello,
im trying to create an A record with the cloudflare API, but im getting every time this error:

ClientException {#791 ▼
  -request: Request {#779 ▶}
  -response: Response {#795 ▶}
  -handlerContext: []
  #message: """
Client error: `POST https://api.cloudflare.com/client/v4/zones/0c63dba01fa136cffd2b8ee3e28959c6/dns_records` resulted in a `400 Bad Request` response:\n
{\n
  "result": null,\n
  "success": false,\n
  "errors": [\n
    {\n
      "code": 1004,\n
      "message": "DNS Validation Error", (truncated...)\n

  #code: 400
  #file: "/var/www/pterodactyl/vendor/guzzlehttp/guzzle/src/Exception/RequestException.php"
  #line: 113
  trace: {▶}
}

This is the PHP laravel code I am using:

$data1 = array(

                'type' => 'A',
                'data' => array(
                    "name" => $subdomain,
                    "content" => 'myip',
                    "ttl" => 120,
                    "proxied" => false,
                )
            );

            try {
                if ($dns->addRecord($zoneID, $data1) !== true) {
                    $this->alert->danger('Failed to create subdomain.')->flash();
                    return redirect()->route('server.subdomain', $server->uuidShort);
                }
            } catch (\Exception $e) {
                dd($e);
                $this->alert->danger('Failed to create subdomain.')->flash();
                return redirect()->route('server.subdomain', $server->uuidShort);
            }

Can someone tell me what i am doing wrong? since i can’t find a clear problem in the error
