@kapa.ai Whats the course of action, when schema validation errors are found on a Airbyute sync. Does the validations get notified? Or does the invalid records be moved to an error table? Or do they get ignored? Airbyte version - 2.2.0 Connector - Apple search Ads Below is for example.

WARN Schema validation errors found for stream _campaigns_report_daily. Error messages: [$.metadata.servingStateReasons: array found, null expected]

Thinking completed Schema Validation Errors in Airbyte Syncs When Airbyte encounters schema validation errors like the one you're seeing:

WARN Schema validation errors found for stream _campaigns_report_daily. 
Error messages: [$.metadata.servingStateReasons: array found, null expected]

Here's what happens: 1. They are Warnings, Not Hard Failures Schema validation errors are typically logged as warnings and do not stop the sync. The sync continues and data is still written to the destination. [Forum: Generic errors] 2. The Data Still Gets Synced Despite the validation warning, the records are generally still passed through to the destination. The destination connector is free to handle the type mismatch in whatever way is most convenient — for example, JSON-serializing an array into a string if the destination can't handle arrays natively. [Data Types docs] 3. What the Error Means in Your Case

$.metadata.servingStateReasons: array found, null expected

means the source (Apple Search Ads) is returning an array for that field, but the connector's declared JSON schema says it should be null. This is a mismatch between the connector's schema definition and what the API actually returns — a common issue when APIs evolve. [Pinterest issue example] 4. Rejected Records (Pro/Enterprise Only) There is a separate concept of rejected records, but this applies specifically to data activation destinations (e.g., HubSpot) on Pro/Enterprise plans. Rejected records are moved to a configured S3 bucket and surfaced in the connection Timeline. This is different from schema validation warnings during a standard ELT sync. [Rejected records docs] Recommended Course of Action The knowledge sources do not contain specific information about Airbyte version 2.2.0 or the Apple Search Ads connector behavior, so I'd recommend also checking the Airbyte GitHub issues for any known issues with that connector. 👍 0 button 👎 0 button ℹ️ Tip: Mention @kapa.ai in the thread for follow-ups or DM the app for 1-to-1 help., with interactive elements
