task-scheduling | NodeJs server using express , Job | Job Scheduling library

I cannot get the contextual reference of the MyOtherService.

Following the docs, this is my code:

I am trying to implement task scheduling as described in Nest documentation, but there is no example with dependency injection for a service that uses scheduling. What I want is to use injected services in recurring tasks, but when I do something like this:

I would like to create a scheduled task for my NestJs application. It should execute every X seconds so I use intervals as described here.

The application makes use of configuration files so I could use keep the interval configurable. But how would I pass in a variable to the Typescript decorator?

NestJs is providing a sample repository for scheduled tasks

So based on the sample I would like to have something like

Question

How do I define Spring Expression Language (SpEL) in groovy spring boot project? (Per spring scheduler crontab @scheduled annotation)

Spring Boot Groovy and Spring EL Scheduler

Per documentation from the web, I'm dinking around with spring scheduler in my groovy spring boot application (2.2.x)

Per this post: Task scheduling using cron expression from properties file

Tried this

I've tried defining my cron expression both as follows:

I have a Google App Engine Flask app that is publishing (via pubsub_v1) to a pubsub every minute using cron.yaml and a Google Compute Engine that is picking up the message, similar to this example. Every minute the GCE app prints out the messages the GAE app sent, but every few minutes I am getting a message in the GCE log saying "Google Compute Engine OS Login is not active." This will happen for 6 - 10 minutes, then the GCE app will start printing out the messages again. What does this message mean and how can I fix it?

When I Google search "Google Compute Engine OS Login is not active", nothing comes up, which is odd for something that appears to be some sort of error.

EDIT:

Here's the GCE script

I need to publish Pub/Sub event in my infrastructure. So, I wrote the background Google Cloud Function that subscribed on topic scan-dead-locks. It will read database and release all crashed not closed locks on documents. This function should be executed periodically every 20 minuets, for example. As I investigated, there is no way to trigger Pub/Sub event directly by App Engine's Cron service. I wrote a python script that should do that (used App Engine's examples), but, the final issue left is that libraries at runtime where not found. So, I've got this error.

And this files.
