maylisdvoodoo opened a new issue, #41439:
URL: https://github.com/apache/airflow/issues/41439
### Apache Airflow version
Other Airflow 2 version (please specify below)
### If "Other Airflow 2 version" selected, which one?
2.6.3
### What happened?
In the Trigger DAG end point, using the DAG conf Parameters form will
incorrectly convert a array of object to an array of string when the parameter
type is defined as:
```
"jobs_list": Param(
[ {"name": "account_name", "country": "country_name"} ],
type="array",
items={
"type": "object",
"properties": {"name": {"type": "string"}, "country_name":
{"type": "string"}},
},
)
```
This can be seen by comparing the value in the field to what is produced in
the generated JSON config :

src="https://github.com/user-attachments/assets/d399af9e-1542-47e5-955d-0c0656358039";>
If this JSON configuration is submitted, then the validation will raise an
error because `"{"name": "account_name", "country": "country_name"}"` is not a
valid object but a string
### What you think should happen instead?
When a parameter is defined as an array of objects, the DAG Conf Parameters
form should generate a value in the Generated JSON config that is an array of
objects.
```
Param(
[ {"name": "account_name", "country": "country_name"} ],
type="array",
items={
"type": "object",
"properties": {"name": {"type": "string"}, "country_name":
{"type": "string"}},
},
),
```
It should be:
```
[ {"name": "account_name", "country": "country_name"} ]
```
instead of
`[ "{"name": "account_name", "country": "country_name"} "]`
### How to reproduce
1. Create a DAG that has a parameter with previous definition of array of
objects : I took it from Airflow Official [Dag
Example](https://airflow.apache.org/docs/apache-airflow/stable/_modules/airflow/example_dags/example_params_ui_tutorial.html)
2. Navigate to the Trigger DAG Run for that DAG
3. Add an object in the DAG Conf Parameters form
4. Note the value in the Generated JSON config has quotes
5. Press submit, and see an error message like:
