"""
Regression test for blitz_api#287.

Bitcoin Core returns the -28 "Loading block index" warmup error as an
HTTP 200 with a JSON-RPC error body. _process_response returned that body
unchanged, so it had an "error" key but no "status" key, and callers doing
`raise HTTPException(result["status"], ...)` crashed with KeyError: 'status'
instead of the HTTPException(425) the startup warmup loop expects.
