Please read Formatting code and log snippets in posts and republish your documents.
Make sure that your redaction does not contain error, like the missing closing brace of each nested_obj, because it makes hard for us to cut-n-paste your document in our installation.
And if I may add
- having values as field name is a bad design because it makes indexing hard if possible at all
- having nested_obj as an object rather than an array makes updates difficult as the right array operators cannot be used
