push metrics to gateway error

[gtbio]

got error:
body="pushed metrics are invalid or inconsistent with existing metrics: pushed metrics must not have timestamps\n"

why is that?

[gtbio]

config.ini:
[config]
push_interval = 60
pushgateway_url = "http://%s10.1.1.29:9091/metrics"
route_map = "/opt/prometheus-pusher/route.map"
#default_route = "prometheus1,prometheus2"

[resource1]
host = "10.1.1.218" # Default
path = "/metrics" # Default
ssl = false # Default
port = 9100

route.map is null

The pushgateway URL looks wrong. Remove %s in the URL and try it again.
