GoogleAIGeminiChatGenerator 400 Request contains an invalid argument issue

[Chance-Obondo]

I am trying to use GoogleAIGeminiChatGenerator for function calling. The code I am using is from the haystack documentation example for using GoogleAIGeminiChatGenerator to respond to questions about the current weather. It was initially working when I tested this on 26/06/2024 but since yesterday 27/06/2024 it has not been working.I am getting the below error

Here is the code i am using, you can run and have a look, please kindly help because I am using Haystack to create an agent that uses function calling.

from haystack.utils import Secret
from haystack.dataclasses.chat_message import ChatMessage
from google.ai.generativelanguage import FunctionDeclaration, Tool

from haystack_integrations.components.generators.google_ai import GoogleAIGeminiChatGenerator

def get_current_weather(location: str, unit: str = "celsius"):
  return {"weather": "sunny", "temperature": 21.8, "unit": unit}

get_current_weather_func = FunctionDeclaration(
    name="get_current_weather",
    description="Get the current weather in a given location",
    parameters={
        "type_": "OBJECT",
        "properties": {
            "location": {"type_": "STRING", "description": "The city and state, e.g. San Francisco, CA"},
            "unit": {
                "type_": "STRING",
                "enum": [
                    "celsius",
                    "fahrenheit",
                ],
            },
        },
        "required": ["location"],
    },
)

tool = Tool(function_declarations= [get_current_weather_func])

gemini_chat = GoogleAIGeminiChatGenerator(model="gemini-pro", api_key=Secret.from_token(""),
                                          tools=[tool])

messages = [ChatMessage.from_user("What is the temperature in celsius in Berlin?")]
res = gemini_chat.run(messages=messages)

weather = get_current_weather(**res["replies"][0].content)
messages += res["replies"] + [ChatMessage.from_function(content=weather, name="get_current_weather")]
res = gemini_chat.run(messages=messages)

for reply in res["replies"]:
    print(reply.content)

I can confirm it.
Our tests are failing https://github.com/deepset-ai/haystack-core-integrations/actions/runs/9705415312/job/26787441393

As a temporary workaround, you can try pinning google-generativeai<0.7.1.

[Chance-Obondo]

Thanks for the suggestion. Which version do you recommend using for google-generativeai ? And is there an issue that you might have noticed that is causing this issue

[anakin87]

Sorry unfortunately pinning google-generativeai<0.7.1 does not work.
Should be investigated better.

[Chance-Obondo]

I agree,I have tried pinning google-generativeai<0.7.1 it hasnt worked on my end. If there is any update please lemme know. But it seems for now the only way is to use a different generator
