This error is thrown when querying Snowflake and indicates that a Snowflake object is unable to be accessed due to a permissions issue. To resolve this, please check that your user has access to (and that none of the user's roles are preventing access to) the Warehouse and Database listed in the connection string, as well as any specified Schema and Tables. Additionally, please check that these values have the correct spelling and casing (as Snowflake is case-sensitive).
