How do I attach a file on email operator in Airflow

Whenever I add the files argument to the email_task I get a failed run.

email_task = EmailOperator(    
           task_id='email_sample_data',    
           to='sample@sample.com',    
           subject='Forecast for the day',    
           html_content= "Sample",
           files=['/home/airflow/sample.html'],    
           dag=dag)

I'm getting an error that the file is not found. Where does airflow pick my file, where do I need to upload a file, and what is the correct syntax for the 'files' argument?

Airflow expect path to be relative to where the DAG file is stored. However since files is templated field you can use template_search_path to provide additional paths that Airflow will look in:

with DAG(
        ...
        template_searchpath = ['/home/airflow/'],
        ) as dag:
    email_task = EmailOperator(
        task_id='email_sample_data',
        to='sample@sample.com',
        subject='Forecast for the day',
        html_content="Sample",
        files=['/home/airflow/sample.html']
    )
