question: the forbidUnknownValues option has no effect

[MickL]

Description

import { IsString, validateSync } from 'class-validator';
import { plainToClass } from 'class-transformer';

class MyClass {
    @IsString()
    id: string;
}

const myObj = {
    id: '123',
    hello: 'world',
};

const validated = plainToClass(MyClass, myObj);

const errors = validateSync(validated, {
    forbidUnknownValues:   true,
});

console.log(errors)

Expected behavior

Should throw an error that hello is not allowed.

Actual behavior

Error-array is empty

You're looking for the whitelist-related options, see Whitelisting:

const errors = validateSync(classedValue, { whitelist: true, forbidNonWhitelisted: true });

forbidUnknownValues serves a different purpose, although the name has led to much confusion #314 #305.

[NoNameProvided]

As answered by @pskopnik, the forbidUnknownValues option serves a different purpose.
