URL: https://github.com/apache/airflow/issues/42439
### Apache Airflow Provider(s)
google
### Versions of Apache Airflow Providers
10.15.0
### Apache Airflow version
2.6.3
### Operating System
Debian
### Deployment
Google Cloud Composer
### Deployment details
_No response_
### What happened
When using `GCSToLocalFilesystemOperator` on a non-existing object, the
resulted exception is regarding a `NoneType` object with no `size` attribute -
which is True, but it would be better to raise an exception that the file
simply does not exist.
### What you think should happen instead
_No response_
### How to reproduce
Use the `GCSToLocalFilesystemOperator` with a non-existing `OBJECT_NAME`
```python
gcs_to_fs = GCSToLocalFilesystemOperator(
task_id="gcs_to_fs",
bucket=BUCKET, # <- exists
object_name=OBJECT_NAME, # <- does not exist
)
```
You'll get an exception similar to this:
```
Traceback (most recent call last):
File

line 118, in execute
file_size = hook.get_size(bucket_name=self.bucket,
object_name=self.object_name)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'size'
