vatsrahul1001 opened a new issue, #48993:
URL: https://github.com/apache/airflow/issues/48993
### Apache Airflow version
3.0.0
### If "Other Airflow 2 version" selected, which one?
_No response_
### What happened?
When we use asset listeners, details are not showing in task logs.
### What you think should happen instead?
_No response_
### How to reproduce
1. Create a file with name `listener_code.py` and pace it in `/flies/dags`
folder
```
from airflow.sdk import Asset
from airflow.listeners import hookimpl
@hookimpl
def on_asset_changed(asset: Asset):
"""Execute when dataset change is registered."""
print("I am always listening for any Dataset changes and I heard that!")
print("Done!")
@hookimpl
def on_asset_created(asset: Asset):
"""Execute when dataset change is registered."""
print("I am always listening for any Dataset created")
print("dataset created")
@hookimpl
def on_task_instance_success(previous_state, task_instance
):
"""Execute when task state changes to SUCCESS. previous_state can be
None."""
print("I am always listening for any TaskInstance to succeed and I heard
that!")
print("Now I fail on purpose...")
@hookimpl
def on_task_instance_running(previous_state, task_instance
):
"""Execute when task state changes to SUCCESS. previous_state can be
None."""
print("task running listener")
print("testing")
```
2. Create a file with name `my_listener_plugin.py` and place it in
`/files/plugin` folder
`from airflow.plugins_manager import AirflowPlugin
from plugins import listener_code
class MyListenerPlugin(AirflowPlugin):
name = "my_listener_plugin"
listeners = [listener_code]
`
4. Put below DAG in files folder
```
from airflow.sdk import Asset
from airflow.decorators import dag, task
from pendulum import datetime
URI = "file://include/bears"
MY_DATASET = Asset(URI)
@dag(
start_date=datetime(2023, 12, 1),
schedule=None,
catchup=False,
tags=["Listeners"],
)
def listener_test():
@task(
outlets=[MY_DATASET],
)
def get_bear():
print("hi")
get_bear()
listener_test()
```
5. Run `breeze start-airflow --executor CeleryExecutor --backend postgres
--dev-mode`
6. Exeute DAG `listener_test`
7. Verify print statement `"I am always listening for any Dataset changes
and I heard that!"` is not visible in task logs. It's only visible in API
server logs with `PydanticSerializationUnexpectedValue`
```
I am always listening for any Dataset changes and I heard that!
Done!
