Describe the bug

Apologies for not providing a Stackblitz as the issue isn't reproducible there. However I can create a minimal reproduction repo if necessary

When using the extendedValidation plugin with cloudflare workers, the following error happens when passing a context object to yoga as the 2nd argument.

"'getOwnPropertyDescriptor' on proxy: trap reported non-configurability for property 'cloudflare' which is either non-existent or configurable in the proxy target"

The error happens with wrangler dev and with the deployed worker.
The error doesn't happen if using a regular runtime like Bun or Node.js.

To Reproduce Steps to reproduce the behavior:

export type CloudflareContext = { env: Env; context: ExecutionContext };

const yoga = createYoga<{ cloudflare: CloudflareContext }>({
	schema,
	context: async ({ request, cloudflare }) => {
		return { cloudflare };
	},
	plugins: [ useExtendedValidation({ rules: [] }) ]
});

export default {
	async fetch(request: Request, env, context) {
		const graphqlContext = {
			request,
			cloudflare: { env, context }
		};
		return yoga(request, graphqlContext);
	}
} satisfies ExportedHandler<Env>;

Expected behavior

No error.

Environment:

• OS: macOs m1
• NodeJS: Workerd, wrangler 3.28.4
• @envelop/* versions: 4.0.0
• @envelop/core: no
• graphql : 16.8.1

Additional context

Investigating further, I found out that if I pass an array instead of an object, everything works (Typescript get lost though).

const yoga = createYoga<[{ request: Request; cloudflare: CloudflareContext }]>(//...)
export default {
	async fetch(request: Request, env, context) {
		const graphqlContext = [{ request, cloudflare: { env, context } }] as const;
		//@ts-expect-error ignore this error
		return yoga(request, graphqlContext) as Response;
	}
} satisfies ExportedHandler<Env>;

I also encountered the same error with SvelteKit, however I did not try the workaround.

Hi, we have made some changes to the way the server context is handled, can you try to update to latest version please?
