graphql-jit and TypeGraphQL union issues.

[reginsmol]

I'm using TypeGraphQL for defining my schema and resolvers. When enabling graphql-jit and fetching a union type I got the following error:
Abstract type Notifiable must resolve to an Object type at runtime for field Notification.notifiable. Either the Notifiable type should provide a \"resolveType\" function or each possible types should provide an \"isTypeOf\" function

It works fine without graphql-jit.

TypeGraphQL union types docs

Union type definition:

const NotifiableUnion = createUnionType({
    name: 'Notifiable',
    types: () => [A,B,] as const,
    resolveType: value => {
        if ('title' in value) {
            return A;
        }

        return B;
    },
});
