How to fix TypeError: Cannot read property 'post' of undefined on Axios with Nestjs cronjob

问题

I tried using cron scheduler to get authentication token every 15 sec(Test purpose) the cron is supposed to call the auth endpoint but I got Exception has occurred: TypeError: Cannot read property 'post' of undefined

 @Cron(CronExpression.EVERY_15_SECONDS)
    async handleCron() {
        //const Primetimeauth = this.PrimetimeAuth()

        const primeAuth = await this.httpService.post('https://clients.com/api/auth', {
            "username": process.env.username,
            "password": process.env.password
        }).toPromise();

        if (primeAuth.status != 200) {
            throw new HttpException({
                message: `Vending Authentication Failed`,
                statusCode: primeAuth.status
            }, HttpStatus.BAD_REQUEST);
        }

        const data = primeAuth.data;

        await this.PrimetimeAuthToken.updateOne({ "_id": "3dtgf1341662c133f0db71412drt" }, {
            "$set":
            {
                token: data.token,
                tokenExpirationTime: data.expires,
                timeTokenReceived: new Date
            }
        });

        return data;
    }

Cron expressions do not work with Request scoped providers, due to possibly being run outside of the context of the request. Due to this, all dependencies come in as undefined. To fix this, you'll need a non-request-scoped provider.
