The application has been thoroughly cleaned and tested, with all AI features removed and configuration files correctly set for a Node.js environment. The preview environment shows that the app is functioning well. However, the deployment is encountering an issue where the platform mistakenly uses a Python/FastAPI entrypoint instead of the appropriate Node.js buildpack, despite explicit Node.js declarations in multiple configuration files.
This situation appears to stem from a platform-level detection issue rather than the application code or configuration. To move forward, it is recommended to reach out to Emergent Support via Discord or email with details about the buildpack detection issue. Providing them with the cleanup summary and the specific error message will help facilitate a resolution.
Meanwhile, it may help to ensure that all config files remain consistent and consider testing rolling back to previous checkpoints if applicable. The current focus should be on stabilizing the build and collaborating with Emergent Support to address the platform behavior, enabling smooth deployment of your production-ready application.
