Since Dublin release, when instantiating a service, there is the need to provide a new "productFamilyId" parameter with a value.

NBI is providing this parameter but without value.

SO transfer that information to AAI but AAI do not accept that this parameter is empty.

The consequence: NBI is not able to delete that service instance (AAI send an error)

Some test show that it is sufficient to put a value in that parameter to retreive a nominal behavior.

We suggest to put the value "1234"
