App builds/runs locally, however returns 500 error in production, failing health check. Logs attached. Observability tab claims the app is running:

[15:38:14] INFO (payload): Connected to MongoDB server successfully!
[15:38:14] INFO (payload): Starting Payload...
[15:38:16] INFO (payload): Payload Admin URL: /admin

Fixed by adding

  "engines": {
    "node": "18"
  }

to package.json… oops
