can't get the miner performance

[huzhengkui]

i set up a env ,and use the curl to test it. But i cant get the data when i use the cmd as follow:

curl http://localhost:4000/api/pools/zec1/miners/tmYHcWLMTxtittvAgoTscLakpCpCu7xXPv2/performance

the err log is as follow:

{
"stateMachine": {
"<>1__state": 0,
curl: (18) transfer closed with outstanding read data remaining
"<>t__builder":

and the err log of miningcore is as follow:
