currently the answer is " default_args are not processed by JINJA"
I don't think this is true. `default_args` just "unpack" at operator
contractor - this is done while parsing the dag not during run time.
I used this code:
```
import pendulum
from airflow import DAG
from airflow.operators.bash import BashOperator
default_args = {
"bash_command": "echo {{ ds }}"
}
with DAG(
dag_id='testing_default_args',
schedule_interval='0 0 * * *',
start_date=pendulum.datetime(2021, 1, 1, tz="UTC"),
catchup=False,
default_args=default_args
) as dag:
run_this = BashOperator(
task_id='run_after_loop',
)
```
and it worked fine:
@leahecole in your code example you try to template `region`, `project_id`
in BigQueryInsertJobOperator but both are not templated fields:

Can you please try it with:
```
class MyBigQueryInsertJobOperator(BigQueryInsertJobOperator):
template_fields: Sequence[str] = (
"region",
"project_id",
) + BigQueryInsertJobOperator.template_fields
```
