A manual relationship is defined using a table that cannot be found in the database.

How to fix

1. Check your options file - locate the manual relationship under manualRelationships
2. Verify table names in both sourceTable and targetTable objects
3. Check spelling and casing - table names are case-sensitive
4. Confirm schema names - ensure you're using the correct schema
5. Verify the tables exist in your source database

Common Issues

Wrong schema: "schema": "dbo" when table is actually in public schema

Case sensitivity: "name": "users" when table is actually Users

Typos: "name": "Costumers" instead of "name": "Customers"

Missing table: Referenced table doesn't exist in the database
