This can break applicationlog getting the stack:

The error means that there was a stackitem, but it can't be serialized and therefore can't be presented in JSON output. Replacing it with NULL or any other element (empty/string with a name) would be wrong because that's not what's on the stack. Proper stack item (like suggested) would be misinterpreted as a real output from the execution, it has to be some error string in case of serialization failure.

But the ones that can't be output to json are iterators (storage); at least what i have ran into (on testnet).

In this way, it will throw exception directly but can't get result stack!
