ETL script that makes request and the log it into a table

Question

  while (true) {
    const result = await sql.query(`
        SELECT TOP (1) *
        FROM  ${originalTable} 
        WHERE IdentifiedState = 0 AND Email <> '' AND AnalyticsAppID = ${AnalyticsAppID}
        ORDER BY InsertDate 
    `);

    if (result.setOfRecords.length == 0) {
        break
    }

    for (let i = 0; i < result.setOfRecords.length; i++) {
        const item = result.setOfRecords[i]
        let UserProperty = {}
        let DBEmail = item['Email'];

        UserFields.forEach(i => {
            let j = i;
            if (i == 'FirstName') { j = 'firstName'; }
            if (i == 'LastName') { j = 'lastName'; }
            if (i == 'Email') {
                item[i] = item[i].split(";")[0];
                item[i] = item[i].split(",")[0];
                item[i] = item[i].replace("$", "@");
                item[i] = item[i].toLowerCase()
                j = 'email';
            }
            UserProperty[j] = item[i];
        });

        if (validateEmail(UserProperty['email']) && UserProperty['email'].length > 10) {
            try {
              await analytics.identify({
                userId: UserProperty['email'],
                traits: UserProperty
              });
              console.log('Successful')
            }
            catch (error) {
              console.log('Error: ', error);
            }
            finally {
              console.log(originalTable, DBEmail, UserProperty['email']);
            }
        }

        await sql.query(`
          UPDATE ${originalTable} 
          SET   IdentifiedState = 1 
          WHERE AnalyticsAppID =  ${AnalyticsAppID} AND Email = '${DBEmail}' `
        );
    }
  }

I have this ETL script, but it ends up in a Timeout exception. I am wondering if there's a need to make the script stronger. Because it loops endlessly and I am wondering what's the best practices with these types of scripts.
