### Apache Airflow version Other Airflow 2 version (please specify below) ### What happened Greetings! Recently I’ve faced a problem. It seems that assigning object, which can’t be serialized to JSON, to the dag_run.conf dict cause critical errors with UI. After executing code example in "How to reproduce": Grid representation of the DAG breaks with following result: <img width="800" alt="Pasted Graphic" src="https://github.com/apache/airflow/assets/79107237/872ccde5-500f-4484-a36c-dce6b7112286";> Browse -> DAG Runs also becomes unavailable. <img width="800" alt="Pasted Graphic 1" src="https://github.com/apache/airflow/assets/79107237/b4e3df0c-5324-41dd-96f3-032e706ab7a9";> Dag itself continues to work correctly, this affects only UI graph and dagrun/list/ I suggest to use custom dictionary with restriction on setting non json values. ### What you think should happen instead Raise an error ### How to reproduce Execute following task. Composer 2 version 2.4.2 Airflow version 2.5.3 ``` @task def test_task(**context): context['dag_run'].conf["test"] = np.int64(1234) ``` ### Operating System Ubuntu 20.04.6 LTS ### Versions of Apache Airflow Providers _No response_ ### Deployment Google Cloud Composer ### Deployment details _No response_ ### 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.
