   In Airflow 3.0.3 the problem arises also using SmtpNotifier:
   
   ```python
   email_notifier = SmtpNotifier(to=['gbonazzoli@xxxxxx.com'])
   
   default_args = {
       'owner': 'gbonazzoli',
       'retries': 0,
       'start_date' : datetime(2023, 7, 1, 0, 0),
       'catchup' : False,  # The catchup defines if the DAG should run for every interval from it’s start time until the current time or not
       'on_failure_callback': [email_notifier],
   }
   ```
   
   I can force the error with a BashOperator pointing to a non existing path (/usr/bin/javaZZ):
   
   ```python
       Show_Java_Version = BashOperator(
           task_id = 'Show_Java_Version',
           bash_command = '/usr/bin/javaZZ --version'
       )
   ```
   
   and the log is:
   
   ```

   ```
   
   The problem remains also if you try to force in airflow.cfg the use of custom templates with:
   
   ```python
   subject_template = /root/airflow/airflow.cfg.subject_template
   html_content_template = /root/airflow/airflow.cfg.html_content_template
   ```
