Thanks in advance

I believe its looking for Client inside Server… Anything Helps, guys.
Thanks

I think it should be npm --prefix folderPath commandToRun

But I might forgo the --prefix flag and just cd into the client directory and run the commands. I think there are some oddities with that flag.

cd ./client && npm i && npm run build

Also, in your app.get I would assume it should be * and not #.

Thanks! I Attempted with the Command you suggested before and it also did not work. I Ended up deploying… but I had to deploy the backend (Heroku) and then the frontend (Netlify)…
Its up and running, but ultimately doesnt address the fact that I was running into those errors when attempting to deploy them together… =(
