Invalid character 'p' after top-level value when add -channelz flag

[sfarwassim]

when I try to run the docker image :
prometheus-nats-exporter:latest -D -channelz -connz -routez -subz -varz -jsz=all -prefix=nats -use_internal_server_id http://localhost:8222
I got these logs
Registered collector for system gnatsd, endpoint: subsz
Registered collector for system gnatsd, endpoint: varz
Registered collector for system gnatsd, endpoint: routez
Registered collector for system gnatsd, endpoint: connz
Registered collector for system nss, endpoint: channelsz
Registered collector for system jetstream, endpoint: all
No certificate file specified; using http.
Prometheus exporter listening at http://0.0.0.0:7777/metrics
ignoring server xxxxxxxx : invalid character 'p' after top-level value

the last line shows only when add the channelz flag also when I add the -serverz flag
