This is not a bug. It is not possible to unpack an Xcom in parsing time
because it does not exist at that moment. Xcom is created at runtime after the
first task is executed:
```python
from datetime import datetime
from airflow.decorators import dag, task
@dag(schedule=None, start_date=datetime(2023, 1, 1), catchup=False)
def testdag():
@task()
def test():
return 'x', 'y'
@task()
def process_x(values):
x = values[0]
print(x)
@task()
def process_y(values):
y = values[1]
print(y)
returned_values = test()
process_x(returned_values)
process_y(returned_values)
testdag()
```
