I can confirm testing with Airflow 2.10.5 that a new bug in the trigger form
was introduced. Using the DAG...
```
import pendulum
from airflow.models.dag import DAG
from airflow.models.param import Param
from airflow.operators.python import PythonOperator
with DAG(
"bug_46858",
schedule=None,
start_date=pendulum.datetime(2021, 1, 1, tz="UTC"),
params={
"some_object": Param(
{},
type="object",
title="JSON entry field",
),
},
) as dag:
def some_code():
print("test")
some_task = PythonOperator(
task_id="some_task",
python_callable=some_code,
)
```
...the JSON element is NOT correctly initialized and as a follow-up issue
the submission fails in JavaScript. This was working with Airflow 2.10.4.
As a workaround - until a fix is landing - the bug is only happening if NO
default value is provided in the form. If you provide a default with...
```
params={
"some_object": Param(
{"key": "value"},
type="object",
title="JSON entry field",
),
},
```
...then the form is working.
I assume it is related to https://github.com/apache/airflow/pull/45315 which
was the only change since Airflow 2.10.4.
