Frontend msg="failed to record query metrics" err="expected one of the *LokiRequest,

Hi,
We have implemented loki using loki-distributed and for past few days, loki (added as data source in grafana) is unable to load labels. We use gcs as backend and I see below error messages in frontend pods. Can you please let me know what could be issue?

thanks,
Raghu
