In version 6.0.1.7, an error has arisen whereby Importacular is reporting an exception when either the incoming value for the Phone Type is blank or there is a Conditional Update Value applied, that would result in the Phone Type being blank. This seems to be conflicting with the Key Fields function that knows not to apply a Phone Type, if the Phone Number field value is blank.
A fix is underway for the next release, but in the meantime, you can apply a Data Transformation as a temporary workaround in order for you to continue importing.
Go in the field settings for the Phone Type field and click on the green circle with the white + and create a new Data Transformation row.
The 'From Source' field needs to be left blank and you can add any value from the 'Change to Target' dropdown.
Importacular really want to add a Phone Type. This Data transformation will do that, but because these fields are Key Fields and linked to the Phone Number field, if the Phone Number field is blank, then Importacular will accept it and will know not to import the Phone Type.
