TypeCheck.Check and TypeCheck.Errors inconsistent with getter methods

[hstaudacher]

We encountered the following problem using the TypeCheck:

When there is a schema defining a property and a class providing this property via a getter function, Check and Errors do different things. Check passes while Errors report errors. Here is a mocha test to reproduce:

    test('TypeBox error is different to check', function () {
        const FooSchema = Type.Object({
            foo: Type.String(),
        });
        class Foo {
            _foo: string;
            constructor(foo: string) {
                this._foo = foo;
            }
            get foo() {
                return this._foo;
            }
        }

        const foo = new Foo('bar');
        const compiled = TypeCompiler.Compile(FooSchema);

        assert.ok(compiled.Check(foo));
        const errors = Array.of(compiled.Errors(foo));
        assert.strictEqual(errors.length, 0);
    });
