PrincipalsOffice opened a new issue #19995:
URL: https://github.com/apache/airflow/issues/19995
### Apache Airflow version
2.2.2 (latest released)
### Operating System
Debian GNU/Linux
### Versions of Apache Airflow Providers
N/A
### Deployment
Other Docker-based deployment
### Deployment details
N/A
### What happened
When I created a TaskInstance object and tried to access its `log_url`
property, an `AttributeError: 'NoneType' object has no attribute 'isoformat'`
exception was raised.
### What you expected to happen
`task_instance.log_url` returns the correct url.
### How to reproduce
```
>>> import pendulum
>>> from airflow.models import DAG, TaskInstance
>>> from airflow.operators.dummy import DummyOperator
>>> dag = DAG("validation_dag", start_date=pendulum.parse("20200101"))
>>> task = DummyOperator(task_id="dummy_task", dag=dag,
task_group=dag.task_group)
>>> task_instance = TaskInstance(task, execution_date=execution_date,
run_id="test")
>>> task_instance.log_url
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File
"/path_to_my_venv/python3.8/site-packages/airflow/models/taskinstance.py", line
651, in log_url
iso = quote(self.execution_date.isoformat())
AttributeError: 'NoneType' object has no attribute 'isoformat'
```
### Anything else
Not sure if the log_url in 2.2.2 even support the execution_date param
anymore. What's the official expected behavior?
