GitHub user dosubot[bot] added a comment to the discussion: Failure on creation of Snowflake dataset due to staging S3 download errors (works in SQL Lab, regression with new connector)
<!-- Answer --> Based on a deep review of Superset's code and recent changes, this isn't a Superset bug—it's an infrastructure or connector config issue. Superset uses SQLAlchemy inspector methods for metadata reflection, which can trigger Snowflake to stage results in S3. If your infra can't reliably access the staging S3 bucket, metadata queries (like dataset creation and column introspection) will fail, while SQL Lab queries may work because they often avoid S3 staging. Superset doesn't implement custom error handling or retries for these S3 staging errors; failures are surfaced directly from the Snowflake connector or network stack, not introduced by Superset itself. No recent PRs or docs indicate a regression or bug in Superset related to this behavior. Troubleshooting should focus on network reliability, connector options, and Snowflake session parameters. If new evidence emerges, it's worth revisiting, but right now this is infra/config, not a Superset bug. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
