openai.chat.completions.create(obj) . The code works against OpenAI but I am getting format errors from Google. First I had to remove the $schema key from each tool function.parameters.$schemaBadRequestError: 400 google error: * GenerateContentRequest.contents: contents is not specifiedobj = {
"messages": [
{
"role": "developer",
"content": "I want to buy a hoodie with a fur lined hood. It needs a full zipper. Near Times Square in NYC. Where can I buy one today at lunch time?"
}

}function.parameters.schema or function.parameters, the latter is the correct way to send it, example: {
"type": "function",
"function": {
"strict": true,
"name": "get_current_temperature",
"description": "Get the current temperature for a specific location",
"parameters": {
"type": "object",

},
"unit": {
"type": "string",
"enum": [
"Celsius",
"Fahrenheit"
],
"description": "The temperature unit to use. Infer this from the user's location."
}
},
"required": [
"location",
"unit"
]
}
}
}function.parameters key as you suggest, see snippet. Google seems to have a different payload format for tool calling, requiring contents instead of messages Am I reading there docs right? https://cloud.google.com/vertex-ai/generative-ai/docs/model-reference/function-calling#examples "tools": [{
