Airflow Jinja Template dag_run.conf not parsing

Question

I have this dag code below.

import pendulum
from airflow import DAG
from airflow.decorators import dag, task
from custom_operators.profile_data_and_update_test_suite_operator import ProfileDataAndUpdateTestSuiteOperator
from custom_operators.validate_data_operator import ValidateDataOperator
from airflow.models import Variable

connstring = Variable.get("SECRET_SNOWFLAKE_DEV_CONNECTION_STRING")

@dag('profile_and_validate_data', schedule_interval=None, start_date=pendulum.datetime(2021, 1, 1, tz="UTC"), catchup=False)
def taskflow():
    
    profile_data = ProfileDataAndUpdateTestSuiteOperator(
        task_id="profile_data",
        asset_name="{{ dag_run.conf['asset_name'] }}",
        data_format="sql",
        connection_string=connstring
    )
    
    validate_data = ValidateDataOperator(
        task_id="validate_data",
        asset_name="{{ dag_run.conf['asset_name'] }}",
        data_format="sql",
        connection_string=connstring,
        trigger_rule="all_done"
    )
    
    profile_data >> validate_data

dag = taskflow()

But the asset_name parameter is showing up the raw string of "{{ dag_run.conf['asset_name'] }}" rather than the configuration that is parsed when you trigger the dag and parsed with jinja.

What am I doing wrong here?
