can you show what your "prod_daily_state_balance" script contains? perhaps you are missing there to propagate the data to the template after you execute the query

Your beforeRender script will be the problem.

Problem 1 is wrong callback and promises handling. If you call connect like this, the callback function is invoked anytime in the future when the script can be already finished.

  connection.connect(
    function (err, conn) {
      if (err) {
        console.error('Unable to connect: ' + err.message);
      } else {
        console.log('Successfully connected to Snowflake.');
        // Optional: store the connection ID.
        connection_ID = conn.getId();
      }
    }
  );

I didn't study your library API, but you probably want to do this

await connection.connect(...)

Problem 2, is that you don't set the req.data anywhere there?
You probably want to do something close to this, but again, I don't know what structures library you use returns.

  const res = await connection.execute({
    sqlText: 'select STATE, STATE_CREDITS, STATE_ACTUAL_CASH, STATE_UNREVEALED, STATE_CUSTOMER_FUNDS FROM SUPERDRAFT_PROD.SD_REPORTS.VW_DAILY_STATE_BALANCE_SDPRO;'
  });
  req.data.rows = res
