@potiuk Sure i'm providing the details. Same issue has occurred even in one of our testing environment. **Apache airflow version:** 2.4.3 **Deployed in Google cloud composer:** 2.1.4 **What happened:** We have one scheduling DAG which will trigger at 12:00 AM. In that DAG we have main task and sub tasks as well. Sub tasks will be created dynamically based on few arguments. When Sub task (which has created dynamically) starts in DAG, I can see instance details as null (means no instance has created for that task. Please refer screenshot 1). So i don't get any logs for that task.

I can see the error log which has occurred under scheduler and time is almost near to stopping of scheduler heart beat.
