Error: Dynamic require of "x" is not supported

Describe the bug

Upgrading to the latest version of sveltekit broke adapter-node for my application. Now the application works in development, but when packaged by adapter-node, it throws `` on start

I’ve commented on that PR with more SvelteKit context to help esbuild maintainers understand why we need this.

I’ve also found https://github.com/evanw/esbuild/issues/946 which appears to be the main issue for why we needed this shim in the first place. I haven’t checked whether the other suggested workarounds in that issue (like the banner one, for example) will still help us here even with the change to __require.

The same thing after https://github.com/sveltejs/kit/pull/6372

var __require = /* @__PURE__ */ ((x) => typeof require !== "undefined" ? require : typeof Proxy !== "undefined" ? new Proxy(x, {
    get: (a, b) => (typeof require !== "undefined" ? require : a)[b]
}) : x)(function (x) {
    if (typeof require !== "undefined")
        return require.apply(this, arguments);
    throw new Error('Dynamic require of "' + x + '" is not supported');
});

...

var crypto_1 = __importDefault(__require("crypto"));

Perhaps the problem is https://github.com/evanw/esbuild/issues/1921
