Description

Currently if I subscribe to Nethermind or Besu clients with 'syncing' subscription it throws the following error:

/node_modules/web3-eth/lib/commonjs/web3_subscriptions.js:132
            const mappedData = Object.fromEntries(Object.entries(data.status).map(([key, value]) => [
                                                                      ^

TypeError: Cannot read properties of undefined (reading 'status')
    at SyncingSubscription._processSubscriptionResult (/node_modules/web3-eth/lib/commonjs/web3_subscriptions.js:132:71) 

This is due to the response format differences. Here is an example of Besu or Nethermind response:

{
  jsonrpc: '2.0',
  method: 'eth_subscription',
  params: {
    subscription: '0x5c68',
    result: {
      startingBlock: '0x9c1ff0',
      currentBlock: '0x9c1ff0',
      highestBlock: '0x9c2b6f'
    }
  }
}

While a Geth node wraps the extra details into one more depth level:

{
  jsonrpc: '2.0',
  method: 'eth_subscription',
  params: {
    subscription: '0x46045714f4037459982d30f6f5c01d90',
    result: {
      syncing: true,
      status: {

        CurrentBlock: 1707865,

      }
    }
  }
}
