Sending a blob file with node

Hello,

I am trying to upload a pdf file to an orderFile table that is linked to another table.

I was able to add a record with a blank file (by removing the Data field from the body) but when I try to add the pdf file I receive an error of "A stream property was found in a JSON request payload. Stream properties are only supported in responses"

Here is the code: 

const request = require("request");
const fs = require("fs");
 
async function sendPost() {
  let myPdf = fs.readFileSync("./sales-invoice-template.pdf");
  let myData = myPdf.toString("base64");
 
  let myBody = {
    Name: "TEST.PDF",
    Data: myData,
    TypeId: myTypeId,
    Version: "1",
    OrderId: myOrderId
  };
 
  let options = {
    method: "POST",
    url: myURL,
    headers: {
      "cache-control": "no-cache",
      "Accept-Encoding": "gzip, deflate",
      Host: myHost,
      "Cache-Control": "no-cache",
      Accept: "*/*",
      "Content-Type": "application/json;odata=verbose",
      Authorization: "Basic XXXXXXXXXXXXXXXXXXXXX"
    },
    body: myBody,
    json: true
  };
 
  request(options, function(error, response, body) {
    if (error) throw new Error(error);
 
    console.log(body);
  });
}
sendPost();
