Nodejs deployment heap exceeded issue

1

So when I try to deploy my nodejs app, I get these errors, any idea why? It was working fine before I made some changes, but the errors are too vague to even start debugging. Any help here? Node v20

You should be running tsc as part of the ‘Build Command’, and then your ‘Start Command’ should be node dist/index.js.

I’m unsure if this is the source of the issue, but it will cut down your startup times. Do you have an Environment Variable or other configuration that is specifying a --max-old-space-size or other Node execution overrides?
