Research direction

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.

Written by the indexing model from the issue text.

Description

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
