Unable to infer GraphQL type from TypeScript reflection system

[vytautas-pranskunas-]

I have args type in separate file

import { ArgsType, Field } from 'type-graphql';

@ArgsType()
export class NotificationsSubscriptionArgs {
    @Field()
    userId: string;
}

and when using it in resolver i get this error:

Error: Unable to infer GraphQL type from TypeScript reflection system. You need to provide explicit type for parameter #1 of 'notification' 
of 'SubscriptionsResolver' class.

however if i add this class to resolver file i do not have any errors

It is interesting because i do have other args files and they do not cause this problem. Difference that they all extend base Args type like:

import { ArgsType, Field } from 'type-graphql';
import { LocalizedRequest } from './localized.request';

@ArgsType()
export class GetByUserIdRequest extends LocalizedRequest {
    @Field()
    userId: string;
}

where LocalizedRwquest is

@ArgsType()
export class LocalizedRequest {
    @Field()
    locale: string;
}

any ideas how to fix it?

Please show your resolver code and how you import those args.
