Not able to access "toJS" helper

Happy Patel

I'm trying to implement chart in my report and when I'm trying to access {{toJS candidates}} helper. It's throwing an error

Error: Missing helper: "toJS"

    at Object.wrapper (/app/node_modules/handlebars/dist/cjs/handlebars/internal/wrapHelper.js:15:19)

But when I'm making one demo playground it's working fine. Is there any solution for this?

Thanks!

You have an older jsreport version I guess.
In this case, the approach here may work for you as well
