`ActionOpenPage` mismatched API response

[salty-flower]

Confirm this is an issue with the Python library and not an underlying OpenAI API

• This is an issue with the Python library

Describe the bug

I got a open_page with "url": null when using official API, so I believe the SDK should count for that. Currently, it was required.

openai-python/src/openai/types/responses/response_function_web_search.py

Line 35 in 847ff0b

url: str

{
  "id": "ws_68c2a7a61e888197b3e9ef5afd5492360a7d1f9fc76c2c97",
  "type": "web_search_call",
  "status": "completed",
  "action": {
    "type": "open_page",
    "url": null
  }
}

To Reproduce

I was using o4-mini-deep-research from Batch API, with web_search_preview enabled.

Alternatively, for OpenAI folks with permission, maybe you could check ws_68c2a7a61e888197b3e9ef5afd5492360a7d1f9fc76c2c97.
