Is there a quick fix to missing helper error with jsreport handlebars nodeJS

[lexdavis030]

trying to use jsreports and jscore node packages to dynamically render a pdf. I get the "Missing helper: "importStylesheet" error. Can anyone help or have seen this?
Running on node 16
with jsreport-core version 3.12.0 and jsreport-handlebars 3.2.1
I've included a screenshot of the error message

Your report seems to use that importStylesheet but you didn't provide it in the template.helpers prop.

Thanks! I got that kinda settled out and now its telling me that my css file isn't there, although I can see it so now I'm trying to get that sorted out.
