译文：API错误：400 InvokeModelWithResponseStream：操作错误 Bedrock运行时：InvokeModelWithResponseStream，https响应错误 状态码：400，请求ID：552da10b-413c-4428-aacb-3a898b5778c9，验证异常：无效的beta标志（请求id：20260721073127248405897rMQtQc3sX2zkzEK2）（请求id：20260721073124189423946c14228f58RFc61ZL）
2. 🎯 原因分析
InvokeModelWithResponseStream操作的验证失败，返回400状态码。3. 💡 解决方案
假设请求是通过AWS SDK调用，修复时移除无效的beta参数示例（以Python boto3为例，移除请求中自定义的无效beta相关参数）：
import boto3
# 初始化Bedrock客户端，不添加额外的无效beta参数
bedrock_client = boto3.client('bedrock-runtime')
try:
# 调用时仅传递必需的合法参数，确保无无效beta标志
response = bedrock_client.invoke_model_with_response_stream(
modelId='your-model-id', # 替换为实际模型ID
body='{"input":"your-input"}' # 替换为实际请求体
)
# 处理响应...
except Exception as e:
print(f"调用失败：{e}")
