Accounts are not indexed to DB

[alexqrid]

Tried to run harvester both in docker and outside docker but the harvester didn't index accounts. How can I fix it? @arjanz

[arjanz]

Could you provide some more context, like which chain, docker-compose environment, error logs etc?

[alexqrid]

I tried both chain: kusama using docker-compose defined below:

docker-compose

version: '3.2'

services:

  harvester-api:
    build: .
    image: &app polkascan-harvester
    ports:
      - '8000:8000'
    volumes:
      - '.:/usr/src/app'
    command: ./start.sh
    environment: &env
      - CELERY_BROKER=redis://redis:6379/0
      - CELERY_BACKEND=redis://redis:6379/0
      - PYTHONPATH=/usr/src/app
      - ENVIRONMENT=dev
    depends_on:
      - redis
      - mysql
      - substrate-node

  harvester-worker:
    build: .
    image: *app
    volumes:
      - '.:/usr/src/app'
    command: celery -A app.tasks worker --loglevel=INFO
    environment: *env
    depends_on:
      - redis
      - mysql

  harvester-beat:
    build: .
    image: *app
    volumes:
      - '.:/usr/src/app'
    command: celery -A app.tasks beat --loglevel=INFO  --schedule="data/celerybeat-schedule" --pidfile="data/celerybeat.pid"
    environment: *env
    depends_on:
      - redis

  harvester-monitor:
    build: .
    image: *app
    ports:
      - '5555:5555'
    command:  flower -A app.tasks --port=5555 --broker=redis://redis:6379/0
    depends_on:
      - redis

  redis:
    image: redis:3.2.11

  mysql:
    image: mysql:latest
    volumes:
      - './data/mysql:/var/lib/mysql'
    ports:
      - '33061:3306'
    environment:
      - MYSQL_ROOT_PASSWORD=root
      - MYSQL_DATABASE=polkascan

  substrate-node:
    image: polkasource/substrate-client:polkadot-latest
    ports:
      - '30333:30333'
      - '9933:9933'
      - '9944:9944'
    command: --rpc-port 9933 --rpc-external --pruning=archive --rpc-cors all --chain=polkadot

I have changed the image of the substrate-node as the image defined in docker-compose.yml in the repo doesn't exist anymore (polkasource/substrate-alexander:latest) and it couldn't be retrieved from dockerhub. As you can see I also started the node in the archive mode.

Indexer database state for the kusama chain

Logs of containters

For the chain polkadot I tried to run indexer outside of the docker, i.e., I installed all dependency on the server and changed appropriate network configs of the app (ip address of the mysql,redis, polkadot node). After successfully indexing a few blocks the indexer started to complain about missing block number 775.

Database state of the polkadot chain

However the main problem is that the blocks, extrinsics, etc. are indexed but accounts are not. As a result running explorer-api can not response on any account info query.

[alexqrid]

@arjanz any suggestions?

[boreyapp]

@alexqrid do you found the solution yet? I meet similar problem like you too. Hope you can seed me some light... http://172.104.177.231:8080/node-template/account

[alexqrid]

@boreyapp Unfortunately I could not and tried subscan but also have had some problems with it. Anyway subscan is better than polkascan, IMHO.
