Failure in source: Please reduce the number of fields requested. Go to the schema tab, select your source, and unselect the fields you do not need.

"Please reduce the number of fields requested" Error This error occurs when the Facebook Graph API considers the total response data too large for a single request. Here's how to resolve it: Primary Fix: Reduce Fields via the Schema Tab 1. In the Airbyte UI, click Connections and select the affected connection. 2. Click the Schema tab. 3. Expand the failing stream (e.g.,

ads_insights

,

ads_insights_action_type

,

ads_insights_region

). 4. Deselect fields you don't need by toggling them off. 5. Click Save changes. 6. When prompted, choose to Refresh the affected streams. [Field Selection Docs] What's Happening Under the Hood The Facebook Marketing connector tries to split large requests automatically by fields. However, if it reaches a point where it cannot split further (e.g., only one non-primary-key field remains) and Facebook still returns an error, it surfaces this as a

config_error

with the message you're seeing. [GitHub source] Additional Tips • Reduce the number of active streams — if you don't need

ads_insights_action_type

,

ads_insights_region

, etc., disable them entirely on the Schema tab. • Check attribution windows — if you have "Include Incrementality" enabled, disabling it can also help, as it adds an extra attribution window that increases data volume. • Reduce the date range — a shorter sync window means less data per request. • Check permissions — a separate error in your logs (

#200 Requires business_management permission

) indicates your access token may also lack required permissions for the

ad_account

stream. You may need to re-authenticate or refresh your token with the correct scopes. [GitHub Issue] image 👍 0 button 👎 0 button ℹ️ Tip: Mention @kapa.ai in the thread for follow-ups or DM the app for 1-to-1 help.
