parse_streaming_error assumed the error body parses to a Hash with a
Hash 'error' value. A bare JSON string body, or a string error value
like {"error": "msg"} (xAI/Grok shape), crashed with TypeError:
String does not have #dig instead of surfacing the provider's message.
Guard the body shape before digging, in the chat_completions, anthropic
and gemini protocols plus the default fallback. Untyped bodies return a
nil status so the real HTTP status from the response env wins.
Fixes crmne#837

What this does
Fixes #837. When a streaming request fails and the error body parses to something other than the typed
{"error": {"type": …, "message": …}}hash — a bare JSON string, or a string error value like{"error": "msg"}(xAI/Grok shape) —parse_streaming_errorcrashed withTypeError: String does not have #dig methodinstead of surfacing the provider's message. The same bodies were already handled fine on the non-streaming path.The old guard
return unless error_data['error']did substring matching on string bodies (String#[]), anddig('error', 'type')recursed into string error values — hence the crash.This adds shape guards before the hash lookups in the
chat_completions,anthropic, andgeminiprotocols plus the default fallback inStreaming. Untyped bodies return anilstatus sobuild_stream_error_responsefalls back to the real HTTP status; the user-facing message still comes fromProvider#parse_error, which already handles string bodies.Type of change
How tested
Regression specs per protocol (typed object, bare string body, string error value) plus end-to-end specs through
handle_failed_responseasserting the provider's actual message surfaces in the raised error. Full suite: 1889 examples, 0 failures.
