Intermittent 5xx errors when downloading islands using AOT Build in Fresh 1.4.2

**Description:**
We've changed our project to use AOT builds + fresh version 1.4.2, this seemed to work fine but we are noticing a small window where islands downloads returns 5xx errors. We are using deno deploy you can see the errors on the attached screenshot below

```text
UnexpectedEof: unexpected EOF during chunk size line: readfile '/src/_fresh/chunk-HXXG4SMD.js.map'

it's important to notice that this error occurs to all islands. The setup of the AOT builds are exactly the same as explained [here](https://fresh.deno.dev/docs/concepts/ahead-of-time-builds)`deno task build + deployctl action`.

A total time of ~4minutes to stabilize
