moco proxy playback seems doesn't work

[xzywait]

I user this config.json below

config.json

[
    {
        "request": {
            "uri": "/test/123"
        },
        "response": {
            "json": {
                "data": "123"
            }
        }
    },
    {
        "request": {
            "uri":"/test/proxy"
        },
        "response": {
            "proxy": {
                "url": "http://localhost:12306/test/123",
                "playback": "playback.json"
            }
        }
    }
]

then I try curl -X GET http://localhost:12306/test/123
got response
{"data":"123"}

however then I try curl -X GET http://localhost:12306/test/proxy
got no response but playback.json seems out of expectation

[ {
  "request" : {
    "version" : "HTTP/1.1",
    "content" : "",
    "headers" : {
      "Host" : "localhost:12306",
      "User-Agent" : "curl/7.54.0",
      "Accept" : "*/*",
      "content-length" : "0"
    }, 
    "method" : "GET",
    "uri" : "/test/proxy"

It seems proxy playback doesn't work , did I make a mistake?

@dreamhead hope you could solve my confusion

@xzywait 请问有结论了吗？我也遇到了这个问题，想把请求和返回体录制下来

It's definitely a bug. It takes me a long time to figure out how to fix it in 43919fc.

@xzywait @huangxd- Would you please help me to verify it in your environment?
