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

@jan_blaha here is the connection

// Use the "beforeRender" or "afterRender" hook
// to manipulate and control the report generation
async function beforeRender(req, res) {
// Load the Snowflake Node.js driver.
var snowflake = require('snowflake-sdk');
// Create a Connection object that we can use later to connect.
var connection = snowflake.createConnection({
account: 'gm36774.eu-west-2',
username: 'dbrody',
password: 'k5MeAqgNs7hgQZ3'
});

// Try to connect to Snowflake, and check whether the connection was successful.
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();
}
}
);

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
}

@bjrmatos @jan_blaha any update on this issue?

jan_blaha

Just name the res differently....

const resFromSql = await connection.execute({

I'm sorry but this is more about javascript general development than jsreport.
We would like to focus this forum primarily on jsreport.

djbrody

@jan_blaha thanks the fixing the error but still don't have data

  const resFromSql = 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

}

bjrmatos

@djbrody you are missing to rename also the places where your old res variable was used, you should update it to the new name resFromSql.

also you seem to use the name detail on your template, so change in the script .rows -> .detail, see bellow for how it should look like:

const resFromSql = 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.detail = resFromSql

please try to analyze your code deeply if you hit any other error.
