# hosting_updateNode_jsBuildSettingsV1

Replaces the build settings stored for the website. Send the full set: node_version is required and every nullable field you omit is stored as null. Creates the settings when none exist yet. This does not start a build. Stored settings drive Git auto-deployment builds; a build started through the API uses the values sent in that request, so to rebuild with corrected settings call Start Node.js build with the same values. Typical fixes: a wrong app_type after auto-detection, or a missing entry_file for express, fastify, nest, nuxt and hono apps.
