Grafana - InfluxDB v2 error

Hello,
I am using InfluxDB v2 on Home Assistant OS 11.4 installed on Raspberry Pi 4B.
Data is flowing because InfluxDB can show some graphs.
I have decided to use Grafana but it show an error.

I am new to InfluxDB and Grafana.so excuse my ignorance.
Perhaps I have set InfluxQL language instead of Flux? Where to check it now?
Or maybe you have other ideas what to verify?

By the way, it i included in configuration.yaml file of Home Assistant:

influxdb:
  api_version: 2
  ssl: false
  host: 192.168.6.15
  port: 8086
  token: A VERY LONG TOKEN==
  organization: Dom
  bucket: Baza
  tags:
    source: HA
  tags_attributes:
    - friendly_name
  default_measurement: units
  exclude:
    entities:
      - zone.home
    domains:
      - persistent_notification
      - person
  include:
    domains:
      - sensor
      - binary_sensor
      - sun
    entities:
      - weather.home

Is something missing perhaps?
