If your organisation has a proxy operating on where this script runs and you are using an private link for snowflake you may encounter an issue resulting in a 403 error when fetching result batches. In such a scenario this is due to the private link not requiring a proxy but the s3 data fetch which snowflake uses requires a proxy, you will need to set the following. export HTTP_PROXY=”http://username:password@proxyserver.company.com:80” Then explicitly call out snowflake itself to not use a proxy export NO_PROXY=”.snowflakecomputing.com” On a windows setup you would use “set” instead of “export” in the command line. |
