Pre-submission Checklist

For tests to work you need a working neo4j instance with the example dataset in docker/db-migration

• Testing: Implement and pass new tests for all new code, while maintaining existing test suite, cargo test.
• Performance: Ensure new code has relevant performance benchmarks, cargo bench

I added one more commit, if that still works on your end, looks good to merge to me! However if you can try removing:

        .allow_origin(Any) // Allow all origins
        .allow_methods(Any) // Allow all HTTP methods
        .allow_headers(Any); // Allow all headers

And that still works... then, let's remove those lines and the import of Any as well before merging 🚀

ACK tested! ✅
