GitHub user komalrajputtrootech edited a discussion: Task exited with return
code 1 with no errors
Hi all,
### Issue
Airflow Version : 2.10.3
I’m running a task in an Airflow DAG that calls a Django function. To
initialize Django, I’m using `django.setup()`.
The task consistently fails with **exit code 1**, but no traceback or error
logs are shown.
### What I’ve Observed
* Logs **before** `django.setup()` are printed correctly.
* Logs **after** `django.setup()` never appear.
* The task exits with return code `1` but without any error or stack trace in
Airflow logs.
Here’s the log snippet:
```
[2025-08-25, 07:35:16 UTC] {operators.py:66} INFO - --------------Initializing
django ------------------------------------------
[2025-08-25, 07:35:17 UTC] {local_task_job_runner.py:266} INFO - Task exited
with return code 1
```
### What I Tried
* Enabled `PYTHONFAULTHANDLER` → still no traceback.
* Wrapped `django.setup()` in try/except with `traceback.print_exc()` → nothing
is printed.
* Adjusted Airflow logging to `DEBUG` → no additional output related to the
crash.
* Verified task environment paths and settings are correct.
### Ask
Has anyone encountered a situation where `django.setup()` fails silently inside
an MWAA/Airflow task?
* How can I capture the real traceback?
* Could this be related to how MWAA handles task logging/subprocesses?
