Graphql with dataloader doesn't return the list, only first item about express-typescript-boilerplate

[jefflequeux]

I was able to fix it by replacing createDataLoader:

export function createDataLoader<T>(obj: ObjectType<T>, method?: string, key?: string): any {
    let repository;
    try {
        repository = getCustomRepository<Repository<any>>(obj);
    } catch (errorRepo) {
        try {
            repository = getRepository(obj);
        } catch (errorModel) {
            throw new Error('Could not create a dataloader, because obj is nether model or repository!');
        }
    }
    return new DataLoader<number, any>(async (ids: number[]) => {
        let items = [];
        if (method) {
            items = await repository[method](ids);
        } else {
            items = await repository.findByIds(ids);
        }
        const gs = _.groupBy(items, key);
        return ids.map(id => gs[id] || []);
    });
}

I've replace:
return ensureInputOrder(ids, items, key || 'id');
by
const gs = _.groupBy(items, key);
return ids.map(id => gs[id] || []);
