Deploy fails silently

[simonw]

https://github.com/simonw/til/runs/6887335796 ran successfully but actually didn't deploy:

/usr/local/lib/node_modules/vercel/dist/index.js:201730
        .filter((b) => Boolean(b.config && b.config.zeroConfig && b.src?.startsWith('api/')))

Here's the bug:

• vercel/vercel#7947

[simonw]

https://github.com/vercel/vercel/releases/tag/vercel%4025.0.0 says:

This release drops support for Node.js 12 in all packages

But my action does this:

til/.github/workflows/build.yml

Lines 84 to 87 in e3ad444

	- name: Setup Node.js
	uses: actions/setup-node@v1
	with:
	node-version: '12.x'

That fixed it.
