在Higress中，是不是不支持？

在Higress中，java后端有个文件流，我发现用higress死活就不行，nginx-ingress就可以没有啥特殊的配置。就一个文件流。前端对接后端直接下载xlsx。是不是不支持？USER : {"authority":"api.xxx.cn","bytes_received":"174","bytes_sent":"87","downstream_local_address":"10.1.2.18:443","downstream_remote_address":"x.x.x.x:64730","duration":"150","istio_policy_status":"-","method":"POST","path":"/report/rms/exportReport/exportReport03","protocol":"HTTP/2","request_id":"0cf20e89-1006-917e-9069-05e98f0a6938","requested_server_name":"api.xxx.cn","response_code":"502","response_flags":"UPE","route_name":"dj-gateway","start_time":"2024-08-20T07:01:29.085Z","trace_id":"e3d446c511f4c2b220d42550de262990","upstream_cluster":"outbound|9000||dj-gateway-svc.bayi-prod.svc.cluster.local","upstream_host":"10.1.2.31:9000","upstream_local_address":"10.1.2.18:57754","upstream_service_time":"-","upstream_transport_failure_reason":"-","user_agent":"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/127.0.0.0 Safari/537.36","x_forwarded_for":"106.14.166.50"}
