   Hello everyone, sorry for not answering later, the upgrade to 2.2.0 was a bit harder than expected with the timetable changes!
   
   Unfortunately, we still experience the same issue. The DAG would trigger as expected, but none of the task would run. I've been able to capture a debug log when the DAG is triggered:
   
   ```
   [2022-02-13 23:02:50,016] {dag.py:2935} INFO - Setting next_dagrun for optimhome_fr_404 to 2022-02-12T23:21:00+00:00
   [2022-02-13 23:02:50,040] {scheduler_job.py:1058} DEBUG - DAG optimhome_fr_404 not changed structure, skipping dagrun.verify_integrity
   [2022-02-13 23:02:50,048] {dagrun.py:622} DEBUG - number of tis tasks for <DagRun optimhome_fr_404 @ 2022-02-11 23:21:00+00:00: scheduled__2022-02-11T23:21:00+00:00, externally triggered: False>: 0 task(s)
   [2022-02-13 23:02:50,048] {dagrun.py:545} INFO - Marking run <DagRun optimhome_fr_404 @ 2022-02-11 23:21:00+00:00: scheduled__2022-02-11T23:21:00+00:00, externally triggered: False> successful
   [2022-02-13 23:02:50,048] {dagrun.py:590} INFO - DagRun Finished: dag_id=optimhome_fr_404, execution_date=2022-02-11 23:21:00+00:00, run_id=scheduled__2022-02-11T23:21:00+00:00, run_start_date=2022-02-13 23:02:50.029131+00:00, run_end_date=2022-02-13 23:02:50.048701+00:00, run_duration=0.01957, state=success, external_trigger=False, run_type=scheduled, data_interval_start=2022-02-11 23:21:00+00:00, data_interval_end=2022-02-12 23:21:00+00:00, dag_hash=d2e4af2c86c72402eebb911e5269818b
   ```
   one intriguing line is `number of tis tasks for <DAG>: 0 task(s)`, except there are tasks on the DAG as you can see on this screenshot

   I've not been able to figure out (yet) where the tasks instances are created in the code. Maybe you can point me to the right direction so I can investigate further?
   
   Thanks a lot!
