Common Errors

​

Invalid credentials

Cause: Connection credentials are wrong or expired. Action: Verify the connection config. Test the connection. For OAuth sources, refresh the token.

​

Connection timeout

Cause: The source or destination is unreachable (network, firewall, IP allowlist). Action: Add the ETL server IP to the source/destination allowlist. Check firewall rules.

​

Permission denied

Cause: The database user lacks required privileges (SELECT, REPLICATION, etc.). Action: Grant the required privileges. See the connector documentation for the exact SQL.

​

Stream not found

Cause: The selected stream does not exist or was removed. Action: Re-discover streams. Update the pipeline configuration.

​

Schema mismatch

Cause: The source schema changed or the destination table has incompatible columns. Action: Reset the pipeline or update the column mapping. For CDC, recreate the publication if tables changed.

​

Rate limit exceeded

Cause: Too many requests to the source API. Action: Reduce sync frequency. Use incremental sync to reduce data volume.
