I am running vn.ask(question="some natual language questions") to query Snowflake table, and it returns the following error.

None
WARNING:snowflake.connector.cursor:execute: no query is given to execute

More information about your setup and steps are necessary here. For this particular question, a SQL statement failed to generate but it could be due to any number of reasons without additional information.

Please provide details on how you set up Vanna (preferably showing all the steps leading up to creation of the vn object).
