Failing to deploy a NestJs api in Railways UI from a Turbo monorepo

Hey all, I have a turbo monorepo repo and inside /apps/api is a NestJs api. I want to use Railway to deploy the api (and db), however I'm struggling to get this to build with nixpacks If I just set the directory to apps/api, build command to yarn run build and start command to yarn run start:prod from the raiway.app UI, the error it spits out says that yarn is not a command It also does not acknowledge npm as a command. What is the proper way to have my yarn run build and yarn run start:prod called from my turbo monorepo's apps/api subfolder?

Also, in the terminal locally, if I run nixpacks plan apps/api, it outputs what looks like a successful plan, knows to setup yarn and such:

}

However, when I run it in the UI separately, the plan does not include the setup step. Just build & start Oh my god I'm an idiot... api was a separate repo. What was being pushed in this main repo was just the current commit hash of that inner repo, not the code itself. This caused a disconnect. Deleted the inner repo and moved the old code to a regular folder of the monorepo instead, and now I get passed the issues. Fingers crossed this was it 🤞
