### Apache Airflow version 2.4.2 ### What happened Create a DAG and set the schedule parameter using a CronTriggerTimeTable instance. Enable the DAG so that there is DAG run data. Try to access the Calendar View for the DAG. An ERR_EMPTY_RESPONSE error is displayed instead of the page. The Calendar View is accessible for other DAGs that are using the schedule_interval set to a cron string instead. ### What you think should happen instead The Calendar View should have been displayed. ### How to reproduce Create a DAG and set the schedule parameter to a CronTriggerTimeTable instance. Enable the DAG and allow some DAG runs to occur. Try to access the Calender View for the DAG. ### Operating System Red Hat Enterprise Linux 8.6 ### Versions of Apache Airflow Providers _No response_ ### Deployment Virtualenv installation ### Deployment details Airflow 2.4.2 installed via pip with Python3.9 to venv using constraints. ### Anything else _No response_ ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
