提交前确认

• 我已经阅读过项目文档

是否是最新版

是,使用最新版

调用的是哪个渠道

antigravity

调用的是哪个模型

claude-opus-4-6-thinking

调用的是哪个格式

openai 格式

具体报错内容

Invalid JSON payload received. Unknown name "custom" at '***.tools[0]': Cannot find field.

错误描述

1. 我在做什么操作时遇到了这个问题
   修复 [Bug]: [Bug]: OpenAI接口调用Claude模型时tools请求报400 custom.input_schema: Field required #388 后重新测试，普通聊天请求（AstrBot自动附带工具定义）报400

2. 我期望的结果是
   工具定义正常发出，模型能正常回复

3. 但实际上发生了
   所有40个工具都报 Unknown name "custom": Cannot find field
   说明新版在转换工具格式时，往每个工具里加了 "custom" 字段，但 Vertex AI 不认识这个字段

补充信息(可选)

No response
