Codex subscription provider fails with Cannot read properties of undefined (reading 'map')

[yodaliu]

When selecting the AI provider as OpenAI Codex (Subscription), OpenAlice returns:

[Codex API error: Cannot read properties of undefined (reading 'map')]

Observed stack/log points to the SDK stream finalizer:

OpenAIError: Cannot read properties of undefined (reading 'map')
caused by: TypeError: Cannot read properties of undefined (reading 'map')
at maybeParseResponse (.../openai/src/lib/ResponsesParser.ts:37:31)
at finalizeResponse (.../openai/src/lib/responses/ResponseStream.ts:367:10)

Likely cause: the ChatGPT Codex subscription endpoint sometimes completes the stream with a response.completed payload that does not include the response.output shape expected by client.responses.stream(). The text deltas have already streamed correctly, but the SDK helper crashes during final response parsing.

Expected behavior:

• Codex subscription streaming should not fail after completion if text deltas were received.
• Real API errors should still be surfaced clearly.

Suggested fix:

• Avoid client.responses.stream() for the Codex subscription path.
• Use raw streaming via:

await client.responses.create({
model,
instructions,
input,
tools,
store: false,
stream: true,
})

• Iterate raw stream events directly.
• Explicitly handle error, response.failed, and response.incomplete events.

Environment:

• OpenAlice: 0.21.0-beta.5
• OpenAI npm SDK: openai@6.33.0
• Provider mode: codex-oauth
