Cannot create index in elasticsearch I use stack ELK

docker-compose:

version: '3'

services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.17.18

    depends_on:
      - elasticsearch

volumes:
    elasticsearch_data:
        driver: local

logstash.conf:

input {
  file {
    path => "/d/FastApiLearning/log.log"
    start_position => "beginning"
  }
}

filter {
  
}

output {
  elasticsearch {
    # hosts => ["host.docker.internal:9200"]
    hosts => ["elasticsearch:9200"]
    index => "fastapi"
    
  }
}

All services are up, at least I didn’t find any errors. There are no critical errors in the logstash container either. What could be the problem?

Output url http://localhost:9600/_node/stats/events?pretty:

  },

    "hosts" : [ "http://elasticsearch:9200" ],
    "username" : "logstash_system"
  },

    "filtered" : 0,
    "out" : 0,
    "duration_in_millis" : 0,
    "queue_push_duration_in_millis" : 0
  }

I understand that my in and out are zero, but why?
