Vercel deployment broken

[dobesv]

Recently I changed this package to use the "standard" environment variables for AWS access. However, in #30 (comment) it was revealed that for Vercel deployment for whatever reason they do not allow those environment variables to be used.

Some fallback environment variables will likely be needed to support Vercel deployment.

Docs:

• https://vercel.com/docs/concepts/projects/environment-variables#reserved-environment-variables
• https://vercel.com/support/articles/how-can-i-use-aws-sdk-environment-variables-on-vercel

Vercel deployments will not work until that is resolved.

This may be as simple as changing vercel.ts like this:

import type { VercelRequest, VercelResponse } from '@vercel/node'
import { createApp } from './app'

// Propage any environment vars APP_AWS_* to AWS_* to workaround
// vercel restriction on environment variables
Object.keys(process.env).filter(k => k.startsWith('APP_AWS_')).forEach(k => {
  process.env[k.substring(4)] = process.env[k];
})

const app = createApp()

export default async function (req: VercelRequest, res: VercelResponse) {
  await app.ready()
  app.server.emit('request', req, res)
}

I am not sure that this is the correct snippet. We should remap S3_ to AWS_.
