Optional properties in an object are still validated

[rfcheung]

If I try to validate an object like the example in the documentation. I get a JSON invalid error.

interface User {
  firstName: string;
  lastName: string;
  age?: number;
}

const schema: JSONSchemaObject = {
  properties: {
    firstName: { type: 'string' } as JSONSchemaString,
    lastName: { type: 'string' } as JSONSchemaString,
    age: { type: 'number' } as JSONSchemaNumeric
  },
  required: ['firstName', 'lastName']
};

const user: User = { firstName: 'Foo', lastName: 'Bar };
this.localStorage.setItem('user', user).subscribe(() => {});

this.localStorage.getItem<User>('user', { schema }).subscribe(res => console.log(res));

Am I doing something wrong?

Tested with 7.2.0

This scenario is tested, and the test is OK.

There is a missing ' after Bar in your code, is that normal?

const user: User = { firstName: 'Foo', lastName: 'Bar };

Ah my bad, but even with the the ', it is still giving JSON invalid. Don't really understand

[cyrilletuzi]

Fixed in v5.3.2, v6.2.1 and v7.2.1.

@rfcheung Thanks for reporting. 👍

Is it possible this problem still continues ? (v9-beta1)

[cyrilletuzi]

No, it's supposed to be fixed. If you found a bug, please file a new issue with a reproduction.
