# X_BUILD_ENTRY_MISSING

## Means

the build target's entry file is not in the app

## Typical cause

an app scaffolded before `x new` wrote `apps/web/server.ts` and `apps/web/prerender.ts`, or one whose `docker/Dockerfile` was deleted — refused before the builder is spawned, because `bun build`'s own "module not found" names no owner

## Fix

the `fix` names the file; `x new <name> --dry-run --json` lists every entry a build needs
