Crashes on iterator comparison

[termontwouter]

The comparison on init.py#L2927 crashes when comparing an iterator with an already listed one having the same fieldname. For example, in my case, both attr_row and attr have the following value:

{
  'type': 'iterable', 
  'iterator': '$.authorization_details[*]', 
  'attr_list': [
    {'type': 'reference', 'value': 'type', 'name': 'type'
    },
    {'type': 'reference', 'value': 'identifier', 'name': 'identifier'
    },
    {'type': 'reference', 'value': 'locations[*
      ]', 'name': 'location'
    },
    {'type': 'reference', 'value': 'actions[*
      ]', 'name': 'action'
    },
    {'type': 'reference', 'value': 'datatypes[*
      ]', 'name': 'datatype'
    },
    {'type': 'reference', 'value': 'privileges[*
      ]', 'name': 'privilege'
    }
  ], 
  'name': 'details'
}

Since this object clearly has no value property, the comparison fails when trying to access it.

Hello @termontwouter,

Thank you for using the SDM-RDFizer. Could you please send me an example mapping and the corresponding data so I can reproduce the issue on my end and fix it?

Sincerely,
Enrique Iglesias
