bug: empty RPC response to eth_getBlockByNumber when using createServer with createMemoryClient #1972
Description
using following snippet to start a server:
import { sepolia } from '@tevm/common'
import { createMemoryClient } from '@tevm/memory-client'
import { createServer } from '@tevm/server'
import { http } from 'tevm'
const client = createMemoryClient({
common: sepolia,
fork: {
transport: http('https://ethereum-sepolia-rpc.publicnode.com')({}),
blockTag: 'latest',
},
})
const server = createServer(client)
server.listen(8545)I then get latest block number with:
> curl http://localhost:8545 -X POST --data '{ "method": "eth_blockNumber" }'
{"jsonrpc":"2.0","method":"eth_blockNumber","result":"0x8d52e5"}⏎ and then try to get the block, but get empty result
> curl http://localhost:8545 -X POST --data '{"method":"eth_getBlockByNumber","params":["0x8d52f3",false],"id":1,"jsonrpc":"2.0"}'
{"method":"eth_getBlockByNumber","result":{},"jsonrpc":"2.0","id":1}however in the server logs I can see the content of the getBlock result, but it seems to be wrapped in Promise which I guess gets serialised to empty object:
response { jsonrpc: '2.0', method: 'eth_blockNumber', result: '0x8d52f3' }
response {
method: 'eth_getBlockByNumber',
result: Promise {
{
