Fix Vercel build: drop functions.runtime partial-semver string#33
Merged
Conversation
The previous "@vercel/node@5" failed the deploy with "Function Runtimes must have a valid version, for example now-php@1.0.0." Vercel's runtime parser now requires a full semver and treats scoped packages as community runtimes. For the built-in @vercel/node runtime we don't need to specify runtime at all — Vercel auto-detects. maxDuration is preserved.

After dropping functions.runtime, the build failed with: "No Output Directory named 'public' found after the Build completed." This is an API-only project (no framework, no static build) but Vercel still expects a public/ directory. Adding a minimal index.html satisfies the build and gives the root domain a useful landing page that points at the relevant endpoints + the repo.

Problem
The first production deploy of
cotrackpro-talkto Vercel failed with:vercel.jsondeclared"runtime": "@vercel/node@5". Vercel's runtime parser now treats scoped packages as community runtimes and requires a full semver (5.1.0, not just5).Fix
Drop the
runtimefield entirely on both function configs. For the built-in@vercel/noderuntime Vercel auto-detects from the framework — no version string needed.maxDuration: 60(cron) andmaxDuration: 30(everything else) are preserved.Test plan
