[GitHub] [airflow] da-dhavalkalola opened a new issue, #32552: Airflow DAG is unable to create Task and skipping all remaining tasks with '0' downstream
da-dhavalkalola opened a new issue, #32552:
URL: https://github.com/apache/airflow/issues/32552
### Apache Airflow version
Other Airflow 2 version (please specify below)
### What happened
We are using Airlfow 2.4.3 version and for Scheduled DAG we found that it is unable to generate task and skipping all remaining tasks with failed status.
==> Below are the part of the DAG code and it is failing after the 'build_activate' task by showing '0' downstream.
`(
start_operator
>> resume_cluster
>> fetch_buildinfo
>> parallel_task1
>> delete_usa_records
>> data_load5
>> data_load6
>> data_load7
>> parallel_task2
>> data_load14
>> data_load15
>> data_load16
>> data_load16_1
>> data_load17
>> data_load17_1
>> get_count
>> build_activate
>> trigger_Fill_rate_QC_report
>> send_notification
>> generate_op
)
generate_op >> trigger_business_US_dag
generate_op >> end_operator`
=> trigger_Fill_rate_QC_report and trigger_business_US_dag :- These two tasks are triggering the different DAG run.
=> generate_op is the branchPythonOperator
==> DAG Tasks Status Image

### What you think should happen instead
It should run all mentioned DAG Tasks and completed successfully.
### How to reproduce
DAG is stopping at the same task every time and skipping all other remaining tasks after that and showing failed status.
### Operating System
Linux

We created trigger_Fill_rate_QC_report task using triggerDagRunOperator and it previous(build_activate) and downstream task (send_notification) is PythonOperator. Then generate_op is BranchPythonOperator which selects in between end_operator and trigger_business_US_dag task.
DAG's graph view is generated correctly and we have refreshed the dag in environment this issue is still persist.

Can you please share the whole code of your dag creation (not just excerpt but the structure, including types of dependencies) Also, share what you mean by " '0' downstream."? Also logs from scheduler when it processes the tasks dependencies, around the time when the last task finishes and you expect it to trigger the task that is not triggered. That would help to help you with the problem, almost for sure it's some kind of typo in some of your code, but it's hard to guess it without seeing all those details.
I will also convert it to a discussion. It looks like a troubleshooting problem, not airflow issue and unless we can get some the more details I asked and can diagnose it better, we will keep it as discussion.

How do you create these tasks? Which operators are you using? Is trigger_Fill_rate_QC_report a new task?
You need to provide an example to reproduce the issue or a result of an investigation you did, otherwise we cannot understand what is the issue and fix it.
