  "message": "Wrong parameter type: output is expected as null. ",
  "stack": [
    "createError(N/error)",
    "renderTxt(/SuiteScripts/Denali_SL_CallPDF.js:50)",

  },
  "id": "",
  "notifyOff": false,
  "userFacing": true
}

go over the parameters of ServerResponse.writeFile

thanks bro!

You can also pass the context into the render TemplateRenderer.renderPdfToResponse()

okay, i am using client script for now to call the suitelet from the button created by user event... is it possible to directly call suitelet from Userevent ??

not really

well okay, i guess then UES-CL-SL is the only way

its easier to put the file generating code in a custom module and share between a user event script and suitelet

right

so the UE can make an ajax call to your suitelet if it is public; you can use the redirect module on before/after sub to take the user to the Suitelet

yeah is it worth to do this, rather than to make a Client script?

Possibly; it depends on what your users need.
