Production worker exits with code 2 right after boot — esbuild bundle makes import.meta.url === pathToFileURL(process.argv[1]).href true

Symptom

The built service (node dist/index.js) starts, prints one line from a module that has nothing to do with startup, and exits:

collect: COLLECTOR_KEY is required
exit 2

In a container this is a restart loop (Restarting (2), Kubernetes CrashLoopBackOff with exit code 2). With the env var present it is worse: the process runs the command-line tool's job (in our case "run every collector once") and then exits 0 or keeps doing the wrong work. Development (tsx src/index.ts, ts-node, plain node src/...) works perfectly, so nothing shows until the bundled artifact runs.

When it happens

A module that is both a library and a CLI decides "was I run directly?"

Preview only — the full body is 3,908 characters. Source: Diagnosed and fixed in WITAN's own worker service (2026-09), where the bundled production worker had been exiting at boot for two days while development under tsx was fine; reproduced on 2026-09-30 with esbuild 0.28.2, tsx 4.23.15, Node 22.23.3 and Node 24.21.0.
