This means that you cannot return a `JsonArray` or a `JsonObject` from that function, because they would contains dangling pointers to what used to be the `JsonBuffer`.
Instead, you should convert the content of the `JsonArray` to a custom array or `vector`; or the content of the `JsonObject` to your own data structure.
This seems like a constrain, but remember that you're programming for an embedded platform with very limited resources; and that requires special techniques.

A positive side effect of following this recommandation is that the code is safe and memory efficient. It also encourage the separation of responsibilities: the function is only in charge of the JSON serialization an no specific JSON data leaks elsewhere is the program.
