AccountUpdate2Operation fields json_metadata and posting_json_metadata can't be None
In AccountUpdate2Operation fields json_metadata and posting_json_metadata have types str | None (with default None). But it seems that those fields can't be None - its not valid operation with None (it could be empty string for example), blockchain doesn't accept transactions with those fields set to None.

Maybe there is more similar issues in other operations with json metadata. Its a bug but low priority
