错误日志是：

```auto
{
“error”: {
“code”: 400,
“message”: “Function call is missing a thought_signature in functionCall parts. This is required for tools to work correctly, and missing thought_signature may lead to degraded model performance. Additional data, function call default_api:search , position 2. please refer to https://ai.google.dev/gemini-api/docs/thought-signatures for more details.”,
“status”: “INVALID_ARGUMENT”
}
}

```

只使用 Helper 出错，如果使用 Creative 没有问题。

官方说这个问题已经解决了，并且提交在 PR 中：[FEATURE: add support for tracking write tokens and anthropic caching … · discourse/discourse@0e6482f · GitHub](https://github.com/discourse/discourse/commit/0e6482fcf4d2a10a27ee55af4701ed2c625cbfc4)

并且代码应该合并到 main 中。
