He !
By reproducing the error, I found the cause.
The problem happens because TanStack Router cannot generate the route tree file inside a subfolder that hasn’t been created yet. Since Git doesn’t keep empty folders, the subfolder is missing in CI and the generation fails.
The error message isn’t very clear, but the fix is:
👉 Add a
.gitkeep file to keep those subfolders in Git.
Example:
This way the generated routeTree.gen.ts file has a valid parent folder, and CI won’t fail. 🚀national-gold•2mo ago
that should be fixable in the generator
ensuring the folder exists
want to create a PR for this?

I've added a check for this to the generator on the Alpha branch. This will be available when Alpha is merged to main.
