Cannot read private member #context from an object whose class did not declare it

[KrayzeeKev]

Version

v20.10.0

Platform

Oracle Enterprise Linux 7

Subsystem

lib/internal/url.js ?

What steps will reproduce the bug?

This occurs when @hapi/wreck is attempting to process a request. The error string above does NOT appear in the source of wreck or anything else in any node_modules directory.

How often does it reproduce? Is there a required condition?

No response

What is the expected behavior? Why is that the expected behavior?

Should not fail.

What do you see instead?

err: TypeError: Client request error: Cannot read private member #context from an object whose class did not declare it

Additional information

I added a console.log(new Error().stack) into @hapi/wreck/lib/index.js to try work out where the error came from. Trace below:

Error

The string context does not appear in @hapi/wreck at all.
The string #context does not appear anywhere in my source or node_modules.
The error message does not appear in that form ANYWHERE I can find in files on my machine. There are several instances WITHOUT the identifier but it must be generated here:
deps/v8/src/common/message-template.h:493: "Cannot read private member % from an object whose class did not declare "
I am guessing this is caused by some inbuilt JavaScript in Node itself? In fact, I'm guessing lib/internal/url.js based on a grep of the source for #context.
This does NOT happen in v18.18.2 and earlier. I switched to v20.9 when it went LTS. Issue persists in v20.10. Have not tried any v20 before v20.9
The version of our source and of node_modules is unchanged between v18.18.2 and v20 (just running new node manually on same deployment tree fails).

This issue goes all the way back to v20.0.0

Have determined this is the result of @hapi/hoek/lib/clone.js which copies an https-proxy-agent options object which contains a parsed URL. This code reproduces the effect:

const url = new URL('http://proxy:443');
const proto = Object.getPrototypeOf(url);
const copy = Object.create(proto);
console.log(copy);

The clone util then goes on to copy all the properties but that's not even necessary. Just the raw object throws the error

/usr/local/node-v20.10.0-linux-x64/bin/node k.js
node:internal/url:844
    return this.#context.href;
                ^

Closing as this is clearly an issue with @Hapi deep cloning and Node is behaving as designed.
