“UIS-0002-400: Batch identity resolution failed” error in Adobe Experience Platform
This article explains the UIS-0002-400: Batch identity resolution failed error in Adobe Experience Platform (AEP). It appears during profile-enabled dataset ingestion, often from Snowflake, even when the batch status shows Success, leading to confusion. The issue occurs because all records contain only one identity. To resolve it, include multiple identities per record.
Description description
Environment
Adobe Experience Platform (AEP)
Issue/Symptoms
- Error shown: UIS-0002-400: Batch identity resolution failed
- The batch status shows Success, which can be confusing and makes it unclear if ingestion actually failed.
- The error occurs daily during profile-enabled dataset ingestion from Snowflake.
- All records in the batch have only one identity.
Resolution resolution
The UIS-0002-400: Batch identity resolution failed error doesn’t mean the data ingestion failed. It happens because each record has only one identity, and the Unified Identity Service (UIS) only processes records with two or more identities to update the identity graph.
To address the issue:
- Check if each record has only one identity. If yes, no action is needed, as UIS skips these records by design. Identity graphs are updated only when a record contains two or more identities.
- Ensure that the batch status is marked as Success. If it shows Success, the data was ingested correctly, even if an error message appears. This behavior is not a bug; it reflects how the Unified Identity Service (UIS) processes records that contain only a single identity.
