`getRandomValues` throwing error `TypeError: Illegal invocation` on Cloudflare Workers

[Brendon Matos]

Environment

unenv@1.7.1
node 18

Reproduction

Unfortunately, runnings wrangler@3 from stackblitz it's still not supported. The original issue was found on Nuxt3 but there the error stops the render of the page, in Nitro this seems like just been ignored.

https://stackblitz.com/edit/github-vk94cj-546phx?file=package.json

Steps:

1. npm run build

2. npm run simulate

3. Open debugger
4. Enable
5. Clear application storage
6. Enter in url

Describe the bug

Seems like when we are in Cloudflare worker environment, this kind of reference destructuring:

unenv/src/runtime/node/crypto/node.ts

Lines 12 to 22 in 2edb8fd

 export const webcrypto = new Proxy( 
   globalThis.crypto as typeof nodeCrypto.webcrypto, 
   { 
     get(_, key: keyof typeof globalThis.crypto | "CryptoKey") { 
       if (key === "CryptoKey") { 
         return globalThis.CryptoKey; 
       } 
       return globalThis.crypto[key]; 
     }, 
   }, 
 ); 

Makes the invoke "Illegal"

Adding these lines makes work like a charm:

export const webcrypto = new Proxy(
  globalThis.crypto as typeof nodeCrypto.webcrypto,
  {
    get(_, key: keyof typeof globalThis.crypto | "CryptoKey") {
      if (key === "CryptoKey") {
        return globalThis.CryptoKey;
      }

+      if (typeof globalThis.crypto[key] === "function") {
+        // @ts-ignore
+        return globalThis.crypto[key].bind(globalThis.crypto);
+      }

      return globalThis.crypto[key];
    },
  },
);
