Chat template is passed

when running Multi-tool-search agent,

Error code: 400 - {'detail': 'Invalid request. Please check the parameters and try again. Details: Chat template is passed with request, but
--trust-request-chat-template is not set. Refused request with untrusted chat template.'}

Investigation:
We intercepted the actual HTTP request being sent and confirmed that NO chat_template parameter is present in the request body. The request only contains:
{
"messages": [{"role": "user", "content": "..."}],
"model": "meta-llama/Meta-Llama-3.1-8B-Instruct"
}

Environment

- LiteLLM version: 1.80.0
- Google ADK (Agent Development Kit)
- Nebius API Base: https://api.studio.nebius.ai/v1
- Models tested:
- meta-llama/Meta-Llama-3.1-8B-Instruct
- meta-llama/Meta-Llama-3.1-8B-Instruct-fast

Start by reproducing the Multi-tool-search agent request with LiteLLM 1.80.0, Google ADK, and the listed Nebius models. Inspect the intercepted HTTP request and the chat-template configuration to determine why the service reports an untrusted template when none is present. Done means the request is accepted and the agent works with both tested models.
