`/v3/accounts/{id}/activities` returns empty for genesis-funded account

[davidyuk]

Description

For a local chain where an account receives funds only via genesis_accounts, the middleware reports a balance for that account but GET /v3/accounts/{account_id}/activities returns an empty list. I expect at least one activity describing the genesis credit (e.g. InternalTransferEvent with payload.kind: "accounts_genesis").

Expected

A response that includes an entry shaped like:

{
  "type": "InternalTransferEvent",
  "height": 0,
  "block_hash": "<genesis micro block hash>",
  "payload": {
    "kind": "accounts_genesis",
    "amount": <genesis amount in aettos>,
    "ref_tx_hash": null
  },
  "block_time": 0
}

(Exact block_hash / amount depend on chain config; the important part is a visible genesis internal-transfer activity consistent with balance.)

Actual

• GET http://localhost:4000/v3/accounts/ak_21A27UVVt3hDkBE5J7rhhqnH5YNb4Y1dqo4PnSybrH85pnWo7E/activities → empty list (no genesis activity).
• The same account still has a non-zero balance via the middleware/node.

Reproduction

1. docker-compose.yml

services:
  middleware:
    image: aeternity/ae_mdw:1.104.6
    ports:
      - '4000:4000'
      - '4001:4001'
      - '3013:3013'
      - '3313:3313'
    volumes:
      - ./aeternity.yaml:/home/aeternity/.aeternity/aeternity/aeternity.yaml

2. aeternity.yaml (mounted as above)

fork_management:
  network_id: ae_superhero_local

  hard_forks:

mining:
  autostart: true

  cuckoo:
    edge_bits: 15
    miners:

3. Steps

1. From the directory that contains docker-compose.yml:
   docker compose up -d
2. Wait until the middleware is healthy (first block mined).
3. Compare:
   • curl -sS 'http://localhost:4000/v3/accounts/ak_21A27UVVt3hDkBE5J7rhhqnH5YNb4Y1dqo4PnSybrH85pnWo7E/activities'
   • curl -sS 'http://localhost:4000/v3/accounts/ak_21A27UVVt3hDkBE5J7rhhqnH5YNb4Y1dqo4PnSybrH85pnWo7E'
