根因分析

Lambda 响应流式传输负载超过了 6 MB 的流式响应限制，导致调用失败。

English

Lambda response streaming payload exceeded the 6 MB limit for streamed responses, causing the invocation to fail.

解决方案

  1. 使用 Lambda 响应流式传输将响应拆分为多个块，每个块发送较小的负载，或在客户端使用分页来分部分请求数据。
  2. 将大响应存储在 S3 中，并向客户端返回预签名 URL，完全避免 Lambda 响应大小限制。

无效尝试

常见但无效的做法:

  1. Increase the Lambda function's timeout or memory. 90% 失败

    The error is about payload size, not execution duration or memory.

  2. Use synchronous Invoke instead of InvokeWithResponseStream. 70% 失败

    Synchronous Invoke has a 6 MB limit as well, and the error will persist.

  3. Compress the response payload with gzip. 60% 失败

    Lambda does not automatically decompress gzip; the client would need to handle it, and the limit applies to the raw payload before compression.
