Backfilling data which has not been ingested into Prometheus can cause the PromQL dashboard to not show Promscale data.

To fix this error, enable the read_recent option for Promscale in the Prometheus configuration's remote_read section. This ensures that backfilled data is shown in the PromQL dashboard:


remote_read:
  - url: "http://<CONNECTOR-ADDRESS>:9201/read"
    read_recent: true
