[I] Missing dependencies between tasks if Airflow Task Group is empty [airflow]
purnachandergit opened a new issue, #47947:
URL: https://github.com/apache/airflow/issues/47947
### Apache Airflow version
2.10.5
### If "Other Airflow 2 version" selected, which one?
_No response_
### What happened?
Airflow is not honouring the task dependecies for a task if the parent is empty task group
### What you think should happen instead?
If the parent of a task is empty task group
Then it should follow the dependency rule of the parent's parent.
### How to reproduce
Define a dag with 5 tasks
A B C D E
C D belongs to task group test
Dependencies between tasks is
A >> B >> test >> E
C >> D
If task group test is not empty, everything is running fine
If task group test is empty
Ideally behaviour should be A >> B>> E
But tasks A, E are running parallely without honouring the dependencies
Graph view is showing the dependencies correctly but execution is being different
### Operating System
Linux
### Versions of Apache Airflow Providers

### Deployment
Other
