go-ethereum: incorrect number of transactions returned

[jbaldwinroberts]

Description

go-ethereum is returning the incorrect number of transactions

Steps to reproduce

func TestHederaParseBlock(t *testing.T) {
	ctx := context.Background()

	ethClient, err := eth.Dial("https://testnet.hashio.io/api")
	require.NoError(t, err)

	block, err := ethClient.BlockByNumber(ctx, big.NewInt(7771665))
	require.NoError(t, err)

	log.Infof("number of block transactions, %v", len(block.Transactions())) // 1

	rpcClient, err := rpc.Dial("https://testnet.hashio.io/api")
	require.NoError(t, err)

	var result map[string]interface{}
	err = rpcClient.Call(
		&result, "eth_getBlockByNumber", toBlockNumArg(big.NewInt(7771665)), true,
	)
	require.NoError(t, err)
	
	log.Infof("number of rpc transactions, %v", len(result["transactions"].([]interface{}))) // 1
}

The above prints 1, whereas https://hashscan.io/testnet/block/7771665 shows 9.

@jbaldwinroberts thank you for bringing this to our attention and for your support.

The difference you're seeing occurs because Hedera Consensus Service Submit Messages are not included in the results when querying block data via the Hedera JSON-RPC API. We will determine the reason shortly. This behaviour is not tied to the Golang client itself.

To retrieve the complete list of transactions stored on a specific block, you can use the following script:

curl -X POST https://testnet.hashio.io/api \
-H "Content-Type: application/json" \
-d '{
    "jsonrpc":"2.0",
    "method":"eth_getBlockByNumber",
    "params": [
        "0x769611",  // Block number in hexadecimal (7771665 in decimal is 0x769611 in hex)
        true
    ],
    "id":1
}'

@jbaldwinroberts To add to @arianejasuwienas point, the above JSON RPC call will return ethereum related as well as crypto transfer transactions, and there is one crypto transfer transaction in that block.
