"Lambda handler not found" error due to change in @architect/architect v10.6.0

[LukeAskew]

Have you experienced this bug with the latest version of the template?

Yes

Steps to Reproduce

1. Upgrade @architect/architect to >=10.6
2. npm run dev
3. See error (occasionally)

Expected Behavior

Arc sandbox should detect the server file and run without issue.

Actual Behavior

There is a race condition between remix watch and void arc() that results in arc intermittently not being able to find the server build artifact. This happens pretty consistently on first boot or if the server/ directory is deleted before the build.

Here's my fix in dev.js. I'm sure there is a cleaner way, but this might help unblock some folks in the meantime:

process.env.PORT = process.env.PORT ?? 3000;
process.env.ARC_LOCAL = process.env.ARC_LOCAL ?? 1;
process.env.ARC_TABLES_PORT = process.env.ARC_TABLES_PORT ?? 5555;

const { watchFile, unwatchFile } = require("fs");
const { join } = require("path");
const arc = require("@architect/architect");

const server = join(__dirname, "server/index.js");

// Wait until the server is built
watchFile(server, { interval: 100 }, (curr, prev) => {
  if (!prev.size && curr.size) {
    void arc();
    unwatchFile(server);
  }
});

Just ran into this issue as well and tried the fix @LukeAskew suggested but it didn't work. Restarting the server seemed to fix the problem though.
