Did you check if you have the field "Phone_UUID__c" in Phone object as it says can't be found on the external system. Navigate to quickfind -> external data sources ->find phone object -> fields and relationship ->find the field. Below images may help you.
Hope this helps ! Mark as solved if it did.

Also check if you have the custom field 'Phone UUID' with API NAme Phone_UUID__c on standard "User" object marked as External ID as below.
Hope this helps!
