An error has occurred during metrics gathering

After updating our stateful set in kubernetes the exporter stopped working with the following error:

An error has occurred during metrics gathering:

3 error(s) occurred:
* collected metric nss_chan_subs_last_sent label:<name:"channel" value:"shop.feature.disabled" > label:<name:"client_id" value:"" > label:<name:"server" value:"http://localhost:8222" > gauge:<value:353 >  was collected before with the same name and label values

We are running nats-streaming v0.14.0 with the exporter as sidecar.

Thanks for the report, looks like this might be the same issue that was fixed via #65
Will push a new release with the fix today, sorry about that.

Thank you, didn't check the MRs. Will reopen if the problem persists after the new release.

@wallyqs when will the new release approximately land?

Sorry for the delay here, have pushed a new version of the exporter where this should be fixed: https://github.com/nats-io/prometheus-nats-exporter/releases/tag/v0.2.2
