PropertyIsUndefined custom Error appears to be flawed

[Cafe137]

Catching it in synchronous code and logging via console.log(error, error.message, error.trace) yields [class u extends Error] undefined undefined.

The message is undefined, and the minified class name does not help too much either.

---

Receiving it as an unhandled rejection is a little bit better:

The promise rejected with the reason "class u extends Error{constructor(){super("Property does not exist in the object")}}".

This is still wrong in multiple ways, but at least I could identify the Error.

---

Lastly, if it worked properly, I think the error message should contain the name of the undefined property, in order to make the message hold useful information.

Code to reproduce:

const { MantarayNode } = require('mantaray-js')

try {
    new MantarayNode().addFork(Buffer.alloc(1), Buffer.alloc(32))
} catch (error) {
    console.log(error, error.message, error.stack)
}

(async () => {
    new MantarayNode().addFork(Buffer.alloc(1), Buffer.alloc(32))
})()
