Unable to execute child process

[PeterTran4]

Hi all, I've been attempting to execute this child process but after much research on both the github and Stackoverflow, still stumped.

Here is my code that is throwing an error.

const officeToPdfPath = 'C:\\\\Users\\ptran\\Desktop\\expressTesting\\OfficeToPDF.exe';
const uploadsPath = 'C:\\\\Users\\ptran\\Desktop\\expressTesting\\uploads';
let command;
let outputName =  currentDate.getTime() + "converted.pdf"
command = `${officeToPdfPath} ${uploadsPath}\\${filename} ${uploadsPath}\\${outputName}`;
return new Promise((resolve, reject) => {
        exec(command, (error, stdout, stderr) => {
          if (error) {
            console.log(error);
            reject(error);
            return;
          }
          if (stderr) {
            console.log(stderr);
            reject(new Error(stderr));
            return;
          }
          else if (stdout) {
            console.log(stdout + "GOOD PDF");
          }
          console.log("Resolve Now");
          console.log(uploadsPath, outputName)
          resolve(uploadsPath + outputName);
});

This is not the full code but seems like the issue is within the exec itself.

My error:

node:internal/process/promises:289
            triggerUncaughtException(err, true /* fromPromise */);
            ^

Node.js v20.11.1

I've double checked as well to make sure that the user is an admin and running both the service as "Local System account"..."allow Service to interact with desktop" and Using a local admin account as well.

Is exec coming from require('child_process')? If so, that is an async function running within a promise. You either need to await/return that promise, or consider using execSync instead. Otherwise it's creating a race condition.
