Error while create pdf stream using html-pdf npm package on Ubuntu Docker

Question

I am getting below error while converting html to pdf using html-pdf npm package on Ubuntu Docker (however it's working fine in my local system Windows and Mac both) -

node:events:491

      throw er; // Unhandled 'error' event

      ^

**Code - ** I tried both APIs but getting same error in both -

1.

htmlPdf.create(htmlContent, htmlToPdfOptions).toStream(function(err: any, stream: { pipe: (arg0: fs.WriteStream) => void; }){
        stream.pipe(fs.createWriteStream('./outputDir/chatTranscript.pdf'));
       });

htmlPdf.create(htmlContent, htmlToPdfOptions)
      .toFile("newPdf.pdf", function(err: any, result: any) {
        if (err) { console.log("Error while generating pdf file - ",err); }
      //     console.log("pdf file generated - ",result);
      //     return; 
     });

**Full Method - **

async function generatePdf() {
  try {
    console.log("Inside generatePdf() ...")
      let  HTMLFilePath = __dirname+"/pdfTemplate.html";

      if (!fs.existsSync(HTMLFilePath)) {
          console.log("file doesn't exists");
      } else {
        console.log("file exists: ",HTMLFilePath);
      }

      const htmlContent = fs.readFileSync(HTMLFilePath, 'utf8');
      const htmlToPdfOptions = {
          "type": ".pdf",
          "height": "650px",
          "width": "850px",
          "renderDelay": 2000,
      };

       const a = await htmlPdf.create(htmlContent, htmlToPdfOptions).toStream(function(err: any, stream: { pipe: (arg0: fs.WriteStream) => void; }){
        stream.pipe(fs.createWriteStream('./outputDir/chatTranscript.pdf'));
       });

       console.log("printing output of html stream");
       console.log("a: ",a);
       return a;

      // htmlPdf.create(htmlContent, htmlToPdfOptions)
      // .toFile("newPdf.pdf", function(err: any, result: any) {
      //     if (err) {
      //       console.log("Error while generating pdf file - ",err);
      //     } 
      //     console.log("pdf file generated - ",result);
      //     return; 
      // });
  } catch (error) {
      console.log("error while converting html-to-pdf", error);
  }
}

Earlier Docker container (Ubuntu) was giving "libfontconfig" library error so I added these two lines in Dockerfile -

apt-get update
apt-get install -y libfontconfig

I also checked the permission on the directory where file is getting generated, user has write permission there.
