Unhandled Rejection (TypeError): Cannot convert undefined or null to object

Given something like this:

export class Contact {
    @Length(10, 20)
    subject: string;

    @IsEmail()
    email?: string;

    @ValidateNested()
    phones: Phone[]

}

class Phone {

    @Length(3)
    preffix: string = '';

    @Length(9, 11)
    number: string = "";
}

When you use Field Array and add a new item (phone in this case) and Unhandled Rejection (TypeError): Cannot convert undefined or null to object is thowed.

How to use with ValidateNested?

Hi! First of all, it's one of the most useful packages I used, and thanks very much to the authors!

So my question is how to use it with ValidateNested decorator (embedded classes)?

Sample code:

export class User {
  @IsString()
  @IsNotEmpty()
  email: string;

  @IsString()
  @IsNotEmpty()
  password: string;

  @IsDefined()
  @IsNotEmptyObject()
  @IsObject()
  @ValidateNested({
    each: true,
  })
  @Type(() => ProfileDto)
  profile: ProfileDto;
}

(Please assume that ProfileDto is another validation class).

Thank you again for the further support!
