[Loki Log driver] Can not to add labels from json

[budarin]

I have installed and working Log driver but can not add labels from logs
Here is my docker-compose logging option for my service

logging:
            driver: 'loki'
            options:
                loki-url: http://host.docker.internal:3100/loki/api/v1/push
                loki-batch-size: 500
                loki-pipeline-stages: |
                    - json:
                        expression:
                            level:
                            msg:
                            timestamp:
                            trace_id: "trace-id"
                    - labels:
                        level:
                        msg:
                        timestamp:
                        trace_id: "trace-id"

logs have those fields but in Grafana I see only labels added with driver by default

for some strange reasons it works after reloading docker machine
