VCL to SO timeout error when using `static(...)` to serve assets

https://app.layer0.co/tristan-lee-hr/layer0-stencil-example/env/default/builds/3

Using Layer0 v4.13.9, I have my router configured as follows:

import { Router } from '@layer0/core/router';

export default new Router()
  .static('www', {
    handler:
      file =>
      ({ cache }) => {
        cache({
          edge: {
            maxAgeSeconds: 60 * 60 * 60 * 365,
            forcePrivateCaching: true,
          },
          browser: {
            maxAgeSeconds: 0,
            serviceWorkerSeconds: 60 * 60 * 24,
          },
        });
      },
  })
  .fallback(({ appShell }) => {
    appShell('www/index.html');
  });

Deployment fails with this error:

If I remove the static(...) call, then deployment succeeds.

I also tried an older version to see if anything changed. Randomly chose 4.6.0 and it succeeds, but took quite a while: :hourglass: Deploying… done (207243ms)
