So I am having an issue generating PDFs from handlebars templates. This is being used on AWS and sometimes in very large volume. Recently I started getting the following error trace and cannot figure out what the true error is. I personally cannot reproduce the error, but it has begun to happen daily. Here is the trace:

ERROR: Error during rendering report: Command failed: /var/task/node_modules/wkhtmltopdf-installer/vendor/wkhtmltopdf --debug-javascript --page-size Letter --margin-bottom 15mm --margin-left 5mm --margin-right 5mm --margin-top 29mm --orientation Portrait --header-spacing 3 --header-html file:////tmp/jsreport-temp/617e1b90-f4d7-11e7-8021-af53ee976040header.html --footer-spacing 3 --footer-html file:////tmp/jsreport-temp/617e1b90-f4d7-11e7-8021-af53ee976040footer.html /tmp/jsreport-temp/617e1b90-f4d7-11e7-8021-af53ee976040.html /tmp/jsreport-temp/617e1b90-f4d7-11e7-8021-af53ee976040.pdf

Here are the fatal level log messages received:

The only thing I notice is that on the Printing step, the last thing it says in Page 5 of 4, and I have no idea why it would do that.

Thanks in advance to anyone who can help shed some light on this.

Hi, I am creating a pf from html string and I am having an image in html which I also want in pdf along with the other content.I am using nodejs for this.

So when i try to create the pdf of the created html string, it gives the following error log:

Error during rendering report: Command failed: D:\nodeJs learning\sails js learning\FirstSailsApp\node_modules\jsreport-wkhtmltopdf\node_modules\wkhtmltopdf-installer\vendor\wkhtmltopdf.exe --disable-local-file-access C:\Users\DCS\AppData\Local\Temp\jsreport-temp\e1400c60-02eb-11e6-ac5f-9166e442552a.html C:\Users\DCS\AppData\Local\Temp\jsreport-temp\e1400c60-02eb-11e6-ac5f-9166e442552a.pdf

Done
Exit with code 1 due to network error: ProtocolUnknownError

Also I have set the wkhtmltopdf's, allowLoaclFilesAccess to true, but yet it starts wkhtmltopdf.exe with --disable-local-file-access command.

What should i do to fix this.

when you try to execute the wkhtmltopdf on OSX you get the following error: cannot execute binary file

after some search on google this seems to be a problem on the wkhtmltopdf file itself, seems that the downloaded version is unable to work on OSX.

I have this in my package.json file:

{
"name": "pdf",
"version": "1.0.0",
"description": "",
"main": "index.js",
"dependencies": {
"jsreport-core": "^1.3.1",
"jsreport-phantom-pdf": "^1.4.4",
"jsreport-jsrender": "^1.0.2",
"jsreport-wkhtmltopdf": "^1.4.0",
"jsreport-handlebars": "^1.1.2"
},
"devDependencies": {},
"scripts": {
"test": "echo "Error: no test specified" && exit 1"
},
"author": "",
"license": "ISC"
}

When I run npm install , I am getting this error

[email protected] postinstall C:\app\node_modules\wkhtmltopdf-installer
node lib/install.js

‼ Global command wkhtmltopdf doesn't seem to work. Downloading wkhtmltopdf localy to /vendor ...

I am running it with microsoft/aspnetcore:2.0-nanoserver-sac2016 docker image as base with node installed.

Hi,

pls can you make small modification, that will return auto-generated file name? Because it is impossible to delete generated files, because names are automatically generated and hash is not returned.

• ex: wkhtmltopdf.js

    response.export = {
        fileName: 'f9dbc8a0-c50f-11e5-8c4c-23b94b1c16ce'
    }; 

      response.headers["Content-Type"] = "application/pdf";
      response.headers["Content-Disposition"] = "inline; filename=\"report.pdf\"";
      response.headers["File-Extension"] = "pdf";

• than, i can in node.js remove created pdf and html in temp folders:

f9dbc8a0-c50f-11e5-8c4c-23b94b1c16ce.pdf
f9dbc8a0-c50f-11e5-8c4c-23b94b1c16ce.html
f9dbc8a0-c50f-11e5-8c4c-23b94b1c16cefooter.html
f9dbc8a0-c50f-11e5-8c4c-23b94b1c16ceheader.html

Thank you

Hi, i want to use local server images, but in your definition, you put there param params.push("--disable-local-file-access");.

Can you make it as option ?

Thank you

function createParams (request, options, id) {
  var params = [];

  params.push("--disable-local-file-access");

  if (options.pageHeight) {
    params.push("--page-height");
    params.push(options.pageHeight);
  }
