"""
Regression test for blitz_api#277.

Bitcoin Core 28+ answers a JSON-RPC 2.0 request with a strict 2.0 response:
a successful reply contains a "result" key but no "error" key. The old code
did `if result["error"] is not None` and crashed with KeyError: 'error'.
get_network_info / get_blockchain_info must handle a success response that
has no "error" key.
