Data Studio Snowflake Connector Error

Hi,

We’re hitting an intermittent Community Connector Error when querying Snowflake (via a Hookit connector) in Looker Studio.

The failure occurs only on initial report render and is tied to the default date range:

  • Breaks when the default is a rolling window (e.g. “Last 7 days”, custom “last 14 days”)

  • Works when the default is a fixed range (e.g. “Yesterday”)

  • If the user manually re-selects the exact same rolling range after load, all components render correctly

The issue affects multiple component types (scorecards, tables, time series, filters) and is consistent across users, browsers, and incognito sessions.

Community Connector Error
Could not connect to Snowflake
traceId: 43b72a6b-7801-455c-8d6f-5d5a75788567
Error ID: f5d7b4ee

What we’ve checked / tried

  • Data source uses owner credentials

  • No recent schema or connector changes

  • Reconnected data source and refreshed fields

  • Tested across multiple users and environments (incl. incognito)

  • Simplified charts and removed filters → still reproducible

  • Changed default date range:

    • rolling windows → fail on load

    • fixed window → works

  • Manual date control interaction consistently resolves the error

The issue is isolated to the initial load state with default rolling date ranges; the same queries succeed once re-triggered via the UI.

Does anyone know what might cause this?

Thanks

I’m not using Snowflake but I’m experiencing a similar error using a different community connector pertaining to bandwidth
