internal server error attempting to call threads.runs with tools

[madc0w]

This call:

import { patch } from 'astra-assistants';
import OpenAI from 'openai';
const originalOpenai = new OpenAI({ apiKey: process.env.OPENAI_API_KEY });
const openaiBot = patch(originalOpenai);

openaiBot.beta.threads.runs.create.bind(openaiBot.beta.threads.runs)(
    threadId,
    {
      assistant_id: process.env.OPENAI_ASSISTANT_ID,
      truncation_strategy: { type: 'last_messages', last_messages: 10 },
      stream: true,
      instructions: config.instructions,
      tools: [
      {
      	type: 'function',
      	function: {
      		name: 'scan_website',
      	},
      },
      ],
      additional_instructions: config.additionalInstructions,
      },
    
)

results in a server error (HTTP 500).
This works fine if no tools are passed.
