Hey there! We've found the following might help you get unblocked faster:

• 🧵 Ignored build step support (npx turbo-ignore)

• 🧵 Environment Variables Silently Dropped/Not Injected

• 🧵 How come my workspace is not recognized?

• 🧵 yarn: command not found

If you find the answer from one of these, please let us know by solving the thread!

Hey there! Are you currently using Railpacks/nixpacks or a Dockerfile?

We're using nixpacks

Interesting, I wonder if the automatic builder is overriding or doing something funky with build steps.
Can I suggest switching to a custom Dockerfile? Extremely simple to set up and I highly recommend the level of control you get over it.
A big lack of "magic box" situations!

Very happy to help you walk through setting one up if you need.

I can definitely work on that at a later time, but for now, any ideas? As fas as I can tell, the configurations & settings for the same app in the production environment are exactly the same, and production builds properly.

Hmmm, in terms of a quick fix im not that sure. Nixpacks is slowly being phased out in favor of Railpacks. From what I see on the nixpacks docs this might help some. https://nixpacks.com/docs/guides/configuring-builds
If its just a simple nextjs site being built, the Dockerfile should be pretty quick to set up.

Otherwise I'm generally unsure as to what could fix that sorry! The community might have more ideas but generally its a good idea to just stick with using a custom Dockerfile.
