why would get_block return an 3010008 error (curl & nodeos)?

Question

I have installed EOS using this - https://eosio-nodeos.readme.io/docs/docker-quickstart

docker pull eosio/eos-dev

And start the EOSIO node:

docker run --rm --name eosio -d -p 8888:8888 -p 9876:9876 -v /tmp/work:/work -v /tmp/eosio/data:/mnt/dev/data -v /tmp/eosio/config:/mnt/dev/config eosio/eos-dev  /bin/bash -c "nodeos -e -p eosio --plugin eosio::wallet_api_plugin --plugin eosio::wallet_plugin --plugin eosio::producer_plugin --plugin eosio::history_plugin --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin --plugin eosio::http_plugin -d /mnt/dev/data --config-dir /mnt/dev/config --http-server-address=0.0.0.0:8888 --access-control-allow-origin=* --contracts-console --http-validate-host=false"

I am now using the API reference here - https://developers.eos.io/eosio-nodeos/reference

This works -

curl --request POST --url http://127.0.0.1:8888/v1/chain/get_info

Giving (after running twice) -

  "virtual_block_net_limit": 6692339,

}

When I try

curl --request POST --url http://127.0.0.1:8888/v1/chain/get_block

{
  "code": 500,
  "message": "Internal Service Error",
  "error": {
    "code": 3010008,
    "name": "block_id_type_exception",
    "what": "Invalid block ID",
    "details": []
  }
}

It seems the EOS single node chain is running. But this basic command fails. I understood eosio was installed automatically as an account.

What could be the cause of this error? Do I need to define an account manually for eosio?

Answer 1

You are not passing any block_id or block_num in your request. Try this:

curl --request POST --url http://127.0.0.1:8888/v1/chain/get_block --data '{"block_num_or_id":"1854"}'

HTH.
