I was able to work around the issue by overriding the default template in
SmtpNotifier and providing a custom html_content.
Here’s an example snippet you can add to your DAG:
```
# Custom SMTP notifier
failure_notifier = SmtpNotifier(
to=["[email protected]"],
subject="Airflow Task Failed: {{ ti.task_id }} in DAG {{ ti.dag_id }}",
html_content="""
<h3>Airflow Task Failure</h3>
<p><b>DAG:</b> {{ ti.dag_id }}</p>
<p><b>Task:</b> {{ ti.task_id }}</p>
<p><b>Execution Date:</b> {{ ts }}</p>
<p><b>Log URL:</b> <a href="{{ ti.log_url }}">{{ ti.log_url
}}</a></p>
"""
)
```
Use the notifier in default_args
```
default_args = {
"on_failure_callback": failure_notifier,
}
```
