@kapa.ai Hi ! Im having a problem when syncying data on a custom Facebook Marketing Ads stream:

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

I have been using this custom stream where I define 'product_id' as a breakdown, without problems.

This error message is coming from the Facebook API and is surfaced by the Facebook Marketing source in Airbyte when Facebook responds with: > “Please reduce the amount of data you’re asking for, then retry your request” > and Airbyte turns it into > “Please reduce the number of fields requested. Go to the schema tab, select your source, and unselect the fields you do not need.” [FB sync issue] Airbyte’s own guidance for this specific situation is exactly what the message says: reduce the number of selected fields in the schema for that stream. You can do this via the Schema tab of your connection: 1. Open the connection. 2. Go to Schema. 3. Expand your custom Facebook Marketing stream (the one with the

product_id

breakdown). 4. Deselect any fields you don’t strictly need (field selection is only available for top‑level fields). [Configuring schema] 5. Save changes and run the sync again (a refresh of the stream may be required depending on your destination). [Configuring schema] From the GitHub issue you can see that even after reducing fields and narrowing the time range, the user still sometimes hit the same Facebook error, which indicates this is largely a Facebook‑side limitation rather than an Airbyte bug. [FB sync issue] The knowledge sources do not provide a more precise workaround for custom breakdowns like

product_id

beyond: • Reducing the number of requested fields in the schema. • Reducing the amount of data requested (e.g., shorter time ranges), and retrying. [FB breakdown error] If you’ve already significantly reduced fields and time windows and still see the error, the docs and forum suggest that the next step is to contact Facebook support, since the underlying cause is on their side and not detailed in the API response.
