容器化AWS SAM CLI遇连接超时，调整SAM_CLI_CONTAINER_CONNECTION_TIMEOUT无效

我正在尝试容器化AWS SAM CLI，对比复杂的DinD方式，选择挂载macOS宿主机的/var/run/docker.sock方案。当前SAM容器能正常启动，调用http://127.0.0.1:5432/hello也能命中容器，但日志报连接超时错误，同时提示Lambda响应不是有效JSON。我用的是AWS官方Hello World API示例，可排除代码问题。已经在docker-compose里设置SAM_CLI_CONTAINER_CONNECTION_TIMEOUT=120，日志显示超时时间已改为120秒，但还是超时。

容器初始日志报错 #

Timed out while attempting to establish a connection
sam_api_test | to the container. You can increase this timeout by setting the
sam_api_test | SAM_CLI_CONTAINER_CONNECTION_TIMEOUT environment variable. The current timeout
sam_api_test | is 20.0 (seconds).
sam_api_test | 2024-04-19 13:45:53,656 | Invalid lambda response received: Lambda response must
sam_api_test | be valid json
