错误信息
status_code=400, InvokeModel: operation error Bedrock Runtime: InvokeModel, https response error StatusCode: 400, RequestID: af711264-cecd-4198-a54e-8e478ecf6290, ValidationException: Unexpected value(s) `redact-thinking-2026-02-12`, `prompt-caching-scope-2026-01-05`, `advisor-tool-2026-03-01` for the `anthropic-beta` header.

AI 解决方案
1. 🌐 错误翻译
原文：ValidationException: Unexpected value(s) `redact-thinking-2026-02-12`, `prompt-caching-scope-2026-01-05`, `advisor-tool-2026-03-01` for the `anthropic-beta` header.
译文：验证异常：`anthropic-beta` 请求头中存在无法识别的值 `redact-thinking-2026-02-12`、`prompt-caching-scope-2026-01-05`、`advisor-tool-2026-03-01`。
2. 🎯 原因分析
anthropic-beta 请求头传入了 Bedrock Runtime 不支持的实验性参数值，被服务端参数校验拦截，触发 ValidationException。InvokeModel 调用时设置的 HTTP 请求头，当前传入的三个日期版本参数均为无效取值。3. 💡 解决方案
// 修复后代码：移除无效的 anthropic-beta 请求头
const invokeModelParams = {
modelId: "your-model-id",
body: JSON.stringify({
messages: [{ role: "user", content: "需要处理的请求内容" }]
}),
// 已删除原 anthropic-beta 头配置
};
const response = await bedrockRuntimeClient.invokeModel(invokeModelParams);
4. 🛡️ 预防措施
anthropic-beta 合法取值，上线前核对参数兼容性。
