ConnectWise is currently returning a NULL value for a phone number, where a contact does not have a phone number selected.

This is normally as a result of no phone number being listed on the contact page.

This issue has been logged with ConnectWise. A work-around has been implemented that will accept the invalid data from ConnectWise (discarding the NULL value) and update Xero with all other contact information.

Please ensure that a Phone Number is selected from the contact numbers in ConnectWise.
