hey , using "array" change my value(array) to a string in another array
`['[{"toto": 5}]']`
```python
from airflow.models import Param
from airflow.operators.python import PythonOperator
from pendulum import today
from airflow import DAG
with DAG(
dag_id="a",
schedule_interval=None,
start_date=today("UTC").add(days=-1),
params={
"x": Param([], type="array"),
}
):
def a(toto):
print(toto)
print(type(toto))
PythonOperator(task_id="toto", python_callable=a, op_kwargs={"toto":
"{{params.x}}"})
```
so I must use `string` until a better support
```python
with DAG(
dag_id="a",
schedule_interval=None,
start_date=today("UTC").add(days=-1),
params={
"x": Param(None, type="string"),
}
):
def a(toto):
toto = json.loads(toto)
print(toto)
PythonOperator(task_id="toto", python_callable=a, op_kwargs={"toto":
"{{params.x}}"})
```
