Configuration Sync Errors:
Error: token_rejected. Authorize Nexonia (Visit Xero)
The Xero token for Nexonia needs to be re-authorized.
Go to the Xero tab > Integration Setup > Edit Parameters > General > Authorize Nexonia > click Visit Xero. You will be forwarded to Xero and be able to request a token to re-authorize the Nexonia integration. Run another configuration sync after doing so to confirm that it is running again.
