A Dependency has validation errors message during a Re-Leased and Xero sync means one or more related records have issues preventing data from flowing between the systems.
Why This Error Occurs
Entities in Re-Leased — such as Contacts, Accounts, Tax Types, Invoices, Attachments, Credit Notes, Payments, and Tracking Options — are interconnected. When an entity doesn't match or isn't recognised in Xero, the dependent records will also fail to sync.
For example: if an invoice references a contact that is invalid or missing in Xero, the invoice sync will fail. You must resolve the contact error first before the invoice will sync.
How to Resolve the Error
Note the ID of the Account, Contact, Invoice, Tax Type, or Tracking Category referenced in the validation message.
Go to the Sync Results Page in Re-Leased and ensure the Linked filter is active.
Enter the ID in the search bar — the record with the validation issue will appear.
Read the Detail message and click More info if you need additional guidance.
Fix the underlying issue described in the message, then re-run the sync.
