const NODE_URL = "CHAINSTACK_NODE_URL";
const provider = new ethers.JsonRpcProvider(NODE_URL);

const traceTransaction = async (txHash) => {
    const trace = await provider.send("debug_traceTransaction", [
      txHash,
      { tracer: "callTracer" }
    ]);
    console.log(JSON.stringify(trace, null, 2));
