URL: https://github.com/apache/airflow/issues/56401
### Apache Airflow version
3.1.0
### If "Other Airflow 2 version" selected, which one?
_No response_
### What happened?
The following DAG produces an error when triggered.
```python
from airflow.sdk import asset
@asset(
schedule=None,
name="custom_name",
)
def function_name(self): ...
```
```

### What you think should happen instead?
The error shouldn't happen and the DAG should run normally.
### How to reproduce
In an AIrflow 3.1.0 instance, add the following DAG and trigger it. The
error will appear in the logs.
```python
from airflow.sdk import asset
@asset(
schedule=None,
name="custom_name",
)
def function_name(self): ...
```
