Hello, @Passerby1011! I'm here to help you with any bugs, questions, or contributions while we wait for a human maintainer. Let's tackle this together!

The 400 error you're encountering with the Gemini model in LobeChat when using plugins on version 1.71.3 is likely due to issues with function declarations in the API request. Specifically, the error message indicates a problem with the JSON payload, particularly with the "GenerateContentRequest.tools[0].function_declarations[0].parameters.properties[_requestBody].properties[data].items.items.type" not being specified when not using "one_of". To resolve this error, it is recommended to disable plugins/function calls when using the Gemini model ^[1]^[2].

gemini模型对插件是兼容不好，所以是不建议使用插件的

The gemini model is not compatible with plug-ins, so it is not recommended to use plug-ins.

应该是bug，之前正常的，现在只要向gemini-2.0-flash-exp发送带function call的请求就会报错：

{
  "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"
  },

}

@Coooolfan 这看着像是 Google 那边禁用的。

@Coooolfan This looks like it is disabled on Google.

@Passerby1011 “谷歌自定义搜索引擎”插件的一点小问题，在下面的 pr 未被合并之前，可以先禁用它。

@Passerby1011 A little bit of a problem with the "Google Custom Search Engine" plugin, you can disable it before the pr below is merged.

I'm having the same issue. It seems other clients have solved it by removing unsupported parameters from the tools: https://github.com/Portkey-AI/gateway/pull/840/files?w=1
