Fallback not working

[joaoh9]

Version

0.5.23

Current behavior

Having problem indexing blocks from arbitrum from a public RPC with fallback implementation.

ponder.config.ts file:

const rpcHttp =
  process.env.PONDER_RPC_URL_PROD?.split(',')
    .filter(el => !!el)
    .map(rpc => http(rpc) as Transport) || [];

const websocket =
  process.env.PONDER_WEBSOCKET_URL_PROD?.split(',')
    .filter(el => !!el)
    .map(ws => webSocket(ws)) || [];

const rateLimitRpc =
  process.env.PONDER_RATELIMIT_RPC_URL_PROD?.split(',')
    .filter(el => !!el)
    .map(rpc => rateLimit(http(rpc), { requestsPerSecond: 1 })) || [];

export default createConfig({
  networks: {
    [process.env.NETWORK as string]: {
      chainId: Number(process.env.CHAIN_ID),
      transport: loadBalance([...rpcHttp, ...websocket, ...rateLimitRpc]),
    },
  },

Getting the following error messages:

URL: https://arbitrum.getblock.io/api_key/mainnet
Request body: {"method":"eth_getBlockByNumber","params":["0x0",true]}

Details: fetch failed
Version: [email protected]

and :

WARN  sync       Failed 'eth_chainId' RPC request after 10 attempts
UnknownRpcError: An unknown RPC error occurred.

Details: Cannot read properties of undefined (reading 'request')
Version: [email protected]

Expected behavior

If one RPC connection fails, another one should be tried. Currently it exits with status code 1
RPC list for easy testing:
PONDER_RPC_URL_PROD=https://arbitrum.llamarpc.com,https://arb1.arbitrum.io/rpc,https://rpc.ankr.com/arbitrum

Can you please add some more info about your ponder.config.ts (which contracts, accounts you have registered)? Based on this error message is seems like the problem is that Ponder is trying to request block 0, rather than the fallback transport itself.

It is 3 custom smart contracts I use in a closed environment (not publicly accessible)
