To make it the easiest for us, please compress the whole application folder of the crashing app.
Upload it to some onedrive,dropbox... and send me the link. I would check what's wrong and then you can remove it.
Thank you for your hints. I finally found that jsreport is based on handlebars library and found that handlebars-intl format numbers and currencies with locale. I installed the last one with npm and use the template functions directly inside my page and it works fine.
Best regards
