Validate single inputs using decorator

[bombillazo]

Hello, how can one use a Decorator validator with a single Arg input?

@Query(() => GraphQLJSONObject, { nullable: true })
  async account(
    @Arg('id')
    @IsId() // <----- this does not work
    id: string,
  ) {
    return account;
}

Nope.

There is no way to do this at all? What are the alternatives?

Create args class:

@ArgsType()
class AccountArgs {
  @Field('id')
  @IsId()
  id: string,
}

@Query(() => GraphQLJSONObject, { nullable: true })
  async account(
    @Args() { id }: AccountArgs 
  ) {
    return account;
}
