bug: self host nextjs docker

まず examples/nextjs-app-router を調査し、そのランタイム設定を、提供されている Dockerfile および Docker Compose サービスと比較します。プロダクションビルドとログインリクエストを再現し、その後、example に文書化された Docker 設定が含まれており、報告された ECONNREFUSED エラーなしで実行できることを確認します。

Describe the bug

Is it possible to add settings that work with docker, it would be great if you could add this with a dockerfile and compose.

 ⨯ Error [FetchError]: Unable to call the API endpoint. Ensure that CORS is set up correctly and that you have provided a valid SDK URL to Ory Elements.
