上記記事のBicep テンプレートでFoundryをデプロイしています
デプロイはすべて成功しましたが、Azure AI SearchをAgentから利用したときに下記のエラーが出ます

tool_user_error: Error: search_service_request_error; Unable to connect to Azure AI Search Resource. Please ensure the Azure AI Search Connection has the correct endpoint and the search resouce has appropriate network settings for the agents setup. Cannot connect to host <Azure AI Search Name>.search.windows.net:443 ssl:default [DNS server returned answer with no data] RunId: run_zNMxqJuyeuZOuaOsAHZsKfLN

プライベートDNSゾーンは存在していて、プライベートエンドポイントがある仮想ネットワークは仮想ネットワークリンクにセットされています。
サブネットはNSGを外していても変わりません
解消方法はありますでしょうか

    Even with the changes you suggested, the issue did not improve, so we redeployed the environment again. It seems that this problem occurs when attempting to use an existing VNet. Thank you very much for your response.
