ExcelJS Setup In Netsuite Having Issues

[KamranPS]

Hi Devs,

I am trying to use the ExcelJS library in Netsuite but facing a lot of issues with the setup. I downloaded the exceljs.min.js cdn Cloudflare and attached the file as a 3rd party module in Netsuite SuiteScript File.

In the initial testing module steps, I executed the below code and found the execution occurred successfully

let workbook = new ExcelJS.Workbook();`

log.debug('workbook', workbook);

workbook.creator = 'Ng Wai Foong';
workbook.lastModifiedBy = 'Bot';
workbook.created = new Date(2021, 8, 30);
workbook.modified = new Date();
workbook.lastPrinted = new Date(2021, 7, 27);

log.debug('workbook', workbook);

After that, I added the addWorkSheet code let worksheet = workbook.addWorksheet('New Sheet'); and got the strange and weird error below:

TypeError: Converting circular structure to JSON exceljs

Also, when executing the below code, I am getting the above-mentioned error

await workbook.xlsx.load(salesReportTemplateFile.getContents())

It seems like, there's some issue with the setup. I will be really thankful to you for helping here by resolving the issues in the initial setup.
