gpt-researcher: commit 906e94f19ab69387d6c4c28fa7aa5646068bf65c, v3.3.5

Hi Everyone,

I'm getting the following error when I run gpt-researcher:

ValueError: No embedding data received

Here is my env file:

OPENAI_API_KEY=my-api-key
OPENAI_BASE_URL=https://my.url:/v1
FAST_LLM=openai:openai/gpt-oss-120b
SMART_LLM=openai:openai/gpt-oss-120b
STRATEGIC_LLM=openai:openai/gpt-oss-120b

It is the gpt-oss-120b model being served by vllm. I have confirmed that the following works in langgraph:

llm = ChatOpenAI(
    model="openai/gpt-oss-120b",
    base_url="https://my.url:/v1",
    api_key=SecretStr("my-api-key"),
    verbose=True

And here is the full stacktrace: https://pastebin.com/X3ifeFtc.

Thank you in advance for your help!
