Code

class Repo {
    async getLastFetched(): Promise<number> {
        try {
            return await new Date().getTime();
        }
        catch {
            return 0;
        }
    }

    async getStatus(): Promise<{ status: number } | undefined> {
        return await { status: 0 };
    }
}

class Foo {
    private async getSingleRepoConfirmStep(repos: Repo[]) {
        const repo = repos[0];
        const [status, lastFetched] = await Promise.all([repo.getStatus(), repo.getLastFetched()]);

        let fetchedOn = ''
        if (lastFetched !== 0 && status !== undefined) {
            const goo = `${status.status}`;
            fetchedOn = `Last fetched ${new Date(lastFetched)}`;
        }
    }
}

Expected behavior:
lastFetched is of type number

Actual behavior:
lastFetched is of type number | undefined
