Your code is already quite clean and mostly correct. However, there are some possible improvements and clarifications:

1. Proper JSON Escaping:
JSON.stringify will properly escape special characters, so your approach is valid.

2. Double Stringify/Parse:
If your goal is to ensure a clean JSON structure, you don’t actually need to stringify and then immediately parse again unless you specifically want to remove any non-serializable values (e.g., functions, undefined). For standard objects, it’s redundant, but sometimes used for a « deep copy ».

3. Node References:
Ensure your references to other nodes are correct and that the nodes output the expected data shape.

4. Return Structure:
return [{ json: { … } }] is correct for most workflow automation platforms (like n8n).

Summary:
Your code is correct for generating a clean JSON structure from node outputs. No further escaping is needed if you use JSON.stringify. The double stringify/parse is only needed if you want to sanitize the object. Otherwise, you can just return the contentPackage directly.
