aws sagemaker端点的输入json字符串是否有限制？

Question

我有〜5MB json字符串要发送到我的端点。我正在使用boto3.client从我的python客户端调用端点。它抛出ConnectionResetError。

ConnectionResetError: [WinError 10054] An existing connection was forcibly closed by the remote host

[查看痕迹，我想这是由于json字符串大小引起的。有人可以帮我解决这个问题吗？

最初，我认为问题是由于客户端的请求大小限制所致，但后来我发现这是由于端点服务映像的默认nginx.conf文件中指定的限制所致。

  server {
    listen 8080 deferred;
    **client_max_body_size 5m;**

    keepalive_timeout 5;
    proxy_read_timeout 1200s;

    location ~ ^/(ping|invocations) {
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $http_host;
      proxy_redirect off;
      proxy_pass http://gunicorn;
    }

    location / {
      return 404 "{}";
    }
  }
}
