Error: write EPIPE with wkhtmltopdf + nodejs on Heroku

I'm using wkhtmltopdf as service to download pdf in a web app, in local server work perfectly, but when I send to production on heroku show this error:

Error: write EPIPE
at WriteWrap.onWriteComplete [as oncomplete] (internal/stream_base_commons.js:66:16)   
Emitted 'error' event at:
at errorOrDestroy (internal/streams/destroy.js:98:12)

The code that I'm using is this: 

   const htmlToPdf = async ({ body: { html } }, res) => {
        const decodedHTml = decodeURI(html);
        fs.readFile(path.join(__dirname, "", "style.css"), (err, data)=>    {
            if (error) throw error;
            const style = `<style>${data}</style>`
            wkhtmltopdf(style + decodedHTml, { pageSize: "A4" }).pipe(res);
        });
    };
Solution

  • The error is caused when you have not installed the command line version of wkhtmltopdf since this is just a wrapper.
