superfluous response.WriteHeader call from client_golang #68
Description
Getting this error from lndmon repeatedly in our logs:
2021/03/26 09:06:14 http: superfluous response.WriteHeader call from github.com/prometheus/client_golang/prometheus/promhttp.(*responseWriterDelegator).WriteHeader (delegator.go:58)
Posts like these suggest it would be fixed by updating to a recent version of client_golang
prometheus/statsd_exporter#257
prometheus/client_golang#730
google/cadvisor#2537
thanos-io/thanos#1086
