How do I connect Snowfalke as a new datasource in GX?

I’m trying to add a new snowflake datasource to GX. Could you please help me with the steps to do so? I have tried following Deploying Great Expectations in a hosted environment without file system or CLI — great_expectations documentation and Connect to SQL database Source Data | Great Expectations but was not successful. Can someone pls help me with setting up this connection.

Getting the below error:
ValidationError: {‘data_connectors’: defaultdict(<class ‘dict’>, {‘default_configured_data_connector_name’: {‘value’: {‘assets’: defaultdict(<class ‘dict’>, {‘class_name’: {‘value’: {‘_schema’: [‘Invalid input type.’]}}, ‘schema_name’: {‘value’: {‘_schema’: [‘Invalid input type.’]}}})}}})}
