cdabella opened a new issue, #42524: URL: https://github.com/apache/airflow/issues/42524
### Apache Airflow version 2.10.1 ### If "Other Airflow 2 version" selected, which one? _No response_ ### What happened? Using a DAG Param with a type of `object` and `enum` set to a list of possible objects is reflected as a string in Trigger DAG UI, both in the selector and in the underlying JSON.  When attempting to run the DAG using the value, the DAG will fail to run  ### What you think should happen instead? JSON schemas support enums of any type > Elements in the array might be of any type, including null. (source: https://json-schema.org/draft/2020-12/json-schema-validation#section-6.1.2-3) . They should be configurable and supported by DAG Parameters, and should allow for successful selection and execution of the DAG from the Trigger DAG UI. ### How to reproduce Create the following DAG ```python from airflow.decorators import dag, task from pendulum import datetime from airflow.models.param import Param keys = ["a", "b", "c"] values_display_list = [{"key": key, "value": key.upper()} for key in keys] @dag( start_date=datetime(2024, 1, 1), schedule=None, catchup=False, params={ "x": Param( values_display_list[0], type=["object"], enum=values_display_list, ), }, tags=["example"], ) def example_params(): @task def example_params_task(*, params, **kwargs) -> None: if params: print(f"Params: {params}") else: print("No Params") example_params_task() # Instantiate the DAG example_params() ``` ### Operating System Debian 12 (Bookworm) ### Versions of Apache Airflow Providers apache-airflow==2.10.1+astro.1 ### Deployment Other Docker-based deployment ### Deployment details Astro CLI running Astro Runtime 12.1.0 ### Anything else? I think this issue might be caused by the the trigger templating at https://github.com/apache/airflow/blob/2.10.2/airflow/www/templates/airflow/trigger.html#L77-L86 ### Are you willing to submit PR? - [ ] 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.
