Could you give some more context? Is this a template? Or your own service?

If it's your own service, is it building using a Dockerfile or Railpack?

My own service. Next.js. The build stopped succeeding after skills were added to the project. Before that, the project was building successfully.

Railpack.

Very odd!

• Can you share your build log and more details on exactly what is failing?
• As much of the package.json as possible, but at minimum your node + package manager version
• If it's possible to get an ls of your directory, that would be really helpful as well.
