_parseResponse ({ data, status, statusText, headers }) {
    if (headers['content-type'] !== 'application/json') {
      throw new RpcError(status, statusText, { data })
    }

      )
    }

    if (!has(data, 'result')) {
      throw new RpcError(-32700, 'Missing `result` on the RPC call result')
