Exception in compute code

Hello,
I have written one script to run the code from compute server like-
const fs = require(“fs”);
const RhinoCompute = require(“compute-rhino3d”);
const { off } = require(“process”);
RhinoCompute.url = “http://localhost:6500/”;
compute();
async function compute()
{
const fileName = “D:\Lattice Demo\LatticeInput\steel\K-4882-156-1 REV 1_stockadded_sup.stl”;
offsetValue = 0.1;
try {
const url = “http://localhost:6500/intech/latticestructure/getlatticedesign”;
const options = {
method: ‘POST’,
headers: {
‘Content-Type’: ‘application/json’,
},
body: JSON.stringify([fileName, offsetValue]),
timeout: 100000,
};
console.log(“In Process”)
const response = await fetch(url, options).then(response => response.json()).then(data => console.log(data)).catch(error => console.log(error));

} catch (error) {
    console.error(error.message);
}

}
but for above file getting this error attached below. I’ve also already set the Environment variable for timeout.

Can anyone please help me with this issue?
