🐛 Bug Description

默认助手和自定义助手包含系统提示词时，对gemini2.0-pro-exp的请求会报错：

{
  "error": {
    "message": "[GoogleGenerativeAI Error]: Error fetching from https://******.com/v1beta/models/gemini-2.0-flash-exp:streamGenerateContent?alt=sse: [400 Bad Request] Developer instruction is not enabled for models/gemini-2.0-flash-exp"
  },
  "provider": "google"
}

将提示词调整为空就没事了。只在网上找到一个相关的帖子：https://linux.do/t/topic/490329/74

Hey @Coooolfan! I'm here to help you with any bugs, questions, or contributions. Let's work on solving this issue together while we wait for a human maintainer.

The issue you're encountering with the gemini2.0-pro-exp model is due to the limited support for Tools Calling capabilities in Google Gemini models. The error message indicates an "Invalid JSON payload" because of unsupported JSON schema properties, such as 'default', in the request payload. When you remove the system prompt words, it likely alters the payload to exclude these unsupported properties, thus resolving the error. To fix this, you should disable plugins and function calls in your implementation ^[1].

To continue talking to Dosu, mention @dosu.

@arvinxx 大佬😭 1.71.2 gemini2.0-pro-exp无法调用任何工具，发出带有function call的请求报错：

{
  "error": {
    "message": "[GoogleGenerativeAI Error]: Error fetching from https://******.com/v1beta/models/gemini-2.0-flash-exp:streamGenerateContent?alt=sse: [400 ] Function calling is not enabled for models/gemini-2.0-flash-exp"
