TriggerDagRunOperator not working

[aamster]

I have 2 dags, my_dag_trigger and my_dag. my_dag_trigger should trigger my_dag. It is just not working when I maually run my_dag_trigger using the airflow UI. my_dag is not run. Is there something special I need to do to get my_dag to run?

import datetime

from airflow.decorators import task
from airflow.models import Param
from airflow.models.dag import dag


@dag(
    schedule=None,
    catchup=False,
    start_date=datetime.datetime.now(),
    params={
        'name': Param(
            default=None
        )
    },
    dag_id='my_dag'
)
def my_dag():
    @task
    def my_task(**context):
        print(context['params']['name'])

    my_task()


my_dag()

import datetime

from airflow.decorators import task
from airflow.models.dag import dag
from airflow.operators.trigger_dagrun import TriggerDagRunOperator


@dag(
    schedule=None,
    catchup=False,
    start_date=datetime.datetime.now(),
    dag_id='my_dag_trigger'
)
def my_dag_trigger():
    @task
    def my_task():
        TriggerDagRunOperator(
            task_id='my_task',
            trigger_dag_id='my_dag',
            conf={
                'params': {
                    'name': 'foo!!!'
                }
            }
        )

    my_task()


my_dag_trigger()
