Grafana Agent on Windows not sending logs to Loki

I followed the instructions at Install Grafana Agent in static mode on Windows | Grafana Agent documentation

and my config looks something like this:

server:
  log_level: warn
metrics:
  wal_directory: C:\ProgramData\grafana-agent-wal
  global:
    scrape_interval: 1m
  configs:
    - name: integrations
logs:
  positions_directory: "C:\\ProgramData\\grafana-agent-positions"
  configs:
    - name: windows
      clients:
        - url: https://780249:<api_key>==@logs-prod-021.grafana.net/loki/api/v1/push
      scrape_configs:
      - job_name: windows
        windows_events:
          bookmark_path: "C:\\ProgramData\\grafana-agent-bookmarks\\bookmark.xml"
          use_incoming_timestamp: false
          eventlog_name: "Application"
          xpath_query: '*'
          labels:
            job: windows
integrations:
  windows_exporter:
    enabled: true

But I see nothing in Grafana. Usage is still all zeros and nothing when I run a query. There’s also nothing in the event logs besides a warning about “No where-clause specified for service collector.” The service is healthy and running according to the services mmc.

Is there some other configuration I need to do on the cloud side?
