sh: 1: del: not found - node.js

Question

I'm wondering if you can help me
Failed Heroku deploy. Been looking at other similar stack overflow posts and changing package.json file trying solutions that have worked for others with no luck. I don't think this is a port issue but it could be a package.json issue or something completely different. Any help, tips or advice is greatly appreciated!
Heroku Log:

This is my package.json file:

I have tried clearing cache and deleting and reinstalling node_modules and package-lock.json
I've updated the node and npm version
I'm using Windows 10 and I've also tried it like this:
del dist && babel backend -d dist && cd frontend && npm install && npm run build
rd /s dist && babel backend -d dist && cd frontend && npm install && npm run build
rm -r dist && babel backend -d dist && cd frontend && npm install && npm run build
None of them run get the same sh:1 error
server.js file:
app.listen(config.PORT, () => {
console.log('Server started at http://localhost:5000');
});
config.js
PORT: process.env.PORT || 5001

rd and del are Windows commands, but Heroku doesn't run Windows. You won't be able to use those commands on Heroku.
I suggest using a cross-platform alternative like rimraf insted of platform-specific commands so your scripts will run properly on your local development environment as well as your hosted environment.
Add it to your dependencies and then use something like
npx rimraf dist && babel backend -d dist && cd frontend && npm install && npm run build
