Yarn: node adapter builds with error in entry script

[Jutanium]

What version of astro are you using?

1.4.4

Are you using an SSR adapter? If so, which one?

Node

What package manager are you using?

yarn

What operating system are you using?

Mac

Describe the Bug

After installing the node adapter and running yarn build, the output entry.mjs script contains this line:

import { compile } from 'path-to-regexp';

This results in an error when script is run:

import { compile } from 'path-to-regexp';
^^^^^^^
SyntaxError: Named export 'compile' not found. The requested module 'path-to-regexp' is a CommonJS module, which may not support all module.exports as named exports.

This is fixed by adding path-to-regexp to noExternal before building.

This error does not happen when using npm or pnpm. Yarn seems to build an entirely different entry script, which is shorter but has these additional dependencies.

Yarn:

// entry.mjs
import * as adapter from '@astrojs/node/server.js';
import { escape } from 'html-escaper';
import 'mime';
import 'cookie';
import 'kleur/colors';
import 'string-width';
import 'path-browserify';
import { compile } from 'path-to-regexp';

const ASTRO_VERSION = "1.4.4";
...

pnpm:

// entry.mjs
import * as adapter from '@astrojs/node/server.js';

const ASTRO_VERSION = "1.4.4";
