Handling of queries that return BIGINT

[nvp152]

Why is my query returning a truncated number if the table contains columns with BIGINT.

e.g. -9120127830603665000 vs -9120127830603665327

Based on what I can tell this issue was fixed. I may be missing something obvious. Running version 4.2.1.

This is what I am doing:

const sql = require('msnodesqlv8')
async function main() {
    try {
        var connParamsArr=[];
        connParamsArr.push('Driver=ODBC Driver 18 for SQL Server');
        if(process.env.DB_INSTANCE) {
          connParamsArr.push('Server=' + process.env.SERVICE_HOST + '\\' + process.env.DB_INSTANCE);
        } else {
          connParamsArr.push('Server=' + process.env.SERVICE_HOST + ',' + process.env.SERVICE_PORT);
        }
        connParamsArr.push('Database=dbg_warehouse');
        connParamsArr.push('TrustServerCertificate=Yes');
        connParamsArr.push('Trusted_Connection=Yes');
        connParamsArr.push('Encrypt=Yes');

        var connectionString=connParamsArr.join(';');
        console.log("Connection string:[" + connectionString + "]");

        this.connectionPool = new sql.Pool({
          connectionString: connectionString
        })
        
        await this.connectionPool.promises.open()
        
        var prom = this.connectionPool.promises.query(`select id as bigint_id, concat(id,'') as string_id from table_with_big_columns`)
        var results = await Promise.all([prom])
        var result = results.map(r => r.first[0].bigint_id + ',' + r.first[0].string_id)
        await this.connectionPool.promises.close()
 
        console.dir(result)
       await this.connectionPool.promises.close()
    } catch (err) {
        console.log("Error:" + err);
    }
}
main();
