Hi guys, i'm new to javascript and i'm trying to create a chatbot on discord using gemini to help me develop. I'm having an issue when i try to add history to the session. Here is my the snippet causing the error;

            const chatSession = model.startChat({
                generationConfig: {
                    temperature: 1,
                    topP: 0.95,
                    topK: 64,
                    maxOutputTokens: 8192,
                    responseMimeType: 'text/plain',
                },history: [
                    { role: 'user', parts: [Array] },
                    { parts: [Array], role: 'model' }
                  ],
            });```

The error disappears and it works perfect when i remove the history part. But i couldn't find any solution on web. To make history work
The error i'm getting;
```Error generating response: GoogleGenerativeAIFetchError: [GoogleGenerativeAI Error]: Error fetching from https://generativelanguage.googleapis.com/v1beta/models/gemini-1.5-flash:generateContent: [400 Bad Request] * GenerateContentRequest.contents[0].parts: contents.parts must not be empty.

``` As i said, i'm new to javascript and using generative ai API's so i really don't even know what am i doing. Any help would be appericated, thank you.
