the method eth_blockNumber does not exist/is not available

Question

Hello hope are good ?

• I have my own full node with a ssh tunnel

My code is :

async function test (){

 const url = 'ws://localhost:8546';
  const web3 = new Web3(new Web3.providers.WebsocketProvider(url));
   const a = await web3.eth.getBlockNumber();
  
 console.log(a);
    }

 test();

Return :

the method eth_blockNumber does not exist/is not available

All is synced and working is there a pb ?

Answer 1

This could be because the Ethereum node you are connecting to is not running the JSON-RPC interface on the same port, or that the Ethereum node is not fully synced yet. Make sure that you are connecting to the correct port and that the node is fully synced. Also check if the geth version you are using support the eth_blockNumber method.
