Hello! It sounds like you need to refresh the source schema in Airbyte to detect the new column you added in BigQuery. When you add a new column to your source, Airbyte doesn't automatically detect it immediately. You'll need to manually refresh the source schema to see the new column in the mapping tab. Here's how to do that: 1. In the Airbyte UI, click
Connections and select your BigQuery to HubSpot connection 2. Navigate to the
Schema tab 3. Click
Refresh source schema to fetch the latest schema from your BigQuery source 4. If changes are detected, you'll see them in the
Refreshed source schema dialog where you can review them After refreshing, the new column should appear in your schema mapping. Additionally, depending on your connection's
Detect and Propagate Schema Changes setting, you may need to manually approve the changes before they're applied to your sync. If your setting is configured to "Approve all changes myself," you'll need to review and save the changes before they take effect in the next sync. For more details, see the [Schema change management documentation](
https://docs.airbyte.com/platform/using-airbyte/schema-change-management) and specifically the section on [manually refreshing the source schema](
https://docs.airbyte.com/platform/using-airbyte/schema-change-management#manually-refresh-the-source-schema).
