XLSX Recipe Corrupt excel output (email attachment)

Nazmus-Sadat

Hi guys!
I am trying to send the generated report as an email attachment. However, in the email, the attached excel cannot be opened as it is corrupted/invalid format. I think, it is an file format/data encoding issue because file retrieved from reportResponse['headers']['permanent-link'] works fine.
Here is the code to send email attachment:

   function(reportError, reportResponse, reportBody){
    attachments: [{
    content: Buffer.from(reportResponse.body).toString('base64'),
    type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet",
    filename: "report.xlsx",
    disposition: "attachment"}], }

Also, when I write the content to disk, I face the same issue:
require('fs').writeFileSync("D:\report.xlsx", reportResponse.body);

Any idea?
In which format Jsreport stores the report content in reportResponse? binary?

Thanks.
