The stage you mentioned, sfc-eu-ds1-9-customer-stage, is an internal Snowflake stage assigned to your account. This endpoint is used in the backend to connect to the cloud storage service Snowflake uses for your account. Clients use it for PUT/GET operations and to fetch persisted or large query results.

Please note that these S3 buckets are not directly accessible, so Snowflake cannot share the credentials for them.

However, you upload and download files from a Snowflake internal/external stage, you must use the following minimum versions of the NodeJS driver:

Version 1.6.2 to upload files (using the PUT command) Version 1.6.6 to download files (using the GET command)
