Blank pdf output using jsreport

I know this has got to have some super easy answer but I am just beginning with this stuff and followed this tutorial: https://jsreport.net/blog/pdf-reports-in-sql-server

Except it gives me a blank page as an output with no real error message.

I'm using handlebars and chrome-pdf to do this...

My database connection script is:

const sql = require('mssql');
const config = {
    "user": "user",
    "password": "password",
    "server": "server",
    "database": "database"
}

async function beforeRender(req, res) {
     await sql.connect(config)
    const sqlReq = new sql.Request();
    const recordset = await sqlReq.query(
        `SELECT DBVersion
      ,MinAppVersion
      

  FROM VersionTbl`
    )
    Object.assign(req.data, {Versions: recordset });         
}

I can see it running and connecting properly in the debug tab... and my sql query seems to be correct if I test it directly in the database server.

My template looks like this:

<table>
{{#each Version}}
    <tr>
        <td>{{DBVersion}}</td>
        <td>{{MinAppVersion}}</td>
    </tr>
{{/each}}
</table>

The debug log...

Can any of you smart people tell me what's going wrong? Thanks
