### How to reproduce
Use the below Dag to reproduce the issue:
```python
from airflow.sdk import DAG
from airflow.providers.standard.operators.python import PythonOperator
from datetime import datetime, timedelta
twos_day = datetime.now() - timedelta(days=2)
def native_obj_false(x, y):
return x, y
def check_type(**context):
ti = context["ti"]
pulled_value = ti.xcom_pull(
task_ids="py_native_obj_false", key="return_value"
)
print(f"This is the datatype for the pulled xcom value:
{type(pulled_value)}")
print(f"This is datatype for the 0th index of the xcom value:
{type(pulled_value[0])}")
print(f"This is datatype for the 1st index of the xcom value:
{type(pulled_value[0])}")
assert type(pulled_value[0]) == str and type(pulled_value[1]) == str
default_args = {"owner": "airflow", "depends_on_past": True}
with DAG(
dag_id="native_obj_false",
start_date=twos_day,
schedule=None,
# when set to false only the __str__() method is returned
render_template_as_native_obj=False,
tags=["core", "negative"],
user_defined_macros={
"says_hi": "Hello World!",
"the_planets": [
"Mercury",
"Venus",
"Earth",
"Mars",
"Jupiter",
"Saturn",
"Neptune",
],
"ints": [1, 2, 3, 4, 5],
},
) as dag:
t1 = PythonOperator(
task_id="py_native_obj_false",
python_callable=native_obj_false,
op_args=["{{ says_hi }}", "{{ ints }}"],
)
t2 = PythonOperator(
