### What happened
After upgrading the _apache-airflow-providers-snowflake_ from version
**3.3.0** to **4.0.2**, the SnowflakeCheckOperator tasks starts to throw the
following error:
```
File
"/home/airflow/.local/lib/python3.9/site-packages/airflow/providers/common/sql/operators/sql.py",
line 179, in get_db_hook
return self._hook
File "/usr/local/lib/python3.9/functools.py", line 993, in __get__
val = self.func(instance)
File
"/home/airflow/.local/lib/python3.9/site-packages/airflow/providers/common/sql/operators/sql.py",
line 141, in _hook
conn = BaseHook.get_connection(self.conn_id)
File
"/home/airflow/.local/lib/python3.9/site-packages/airflow/hooks/base.py", line
72, in get_connection
conn = Connection.get_connection_from_secrets(conn_id)
File
"/home/airflow/.local/lib/python3.9/site-packages/airflow/models/connection.py",
line 435, in get_connection_from_secrets
raise AirflowNotFoundException(f"The conn_id `{conn_id}` isn't defined")
airflow.exceptions.AirflowNotFoundException: The conn_id `None` isn't defined
```
### What you think should happen instead
_No response_
### How to reproduce
- Define a _Snowflake_ Connection with the name **snowflake_default**
- Create a Task similar to this:
```
my_task = SnowflakeCheckOperator(
task_id='my_task',
warehouse='warehouse',
database='database',
schema='schema',
role='role',
sql='select 1 from my_table'
)
```
- Run and check the error.
### Anything else
We can workaround this by adding the conn_id='snowflake_default' to the
SnowflakeCheckOperator.
