No key field(s) specified in attribute mapping. inDataDirector import bundle for Pimcore

Question

The DataDirector import claims '[WARNING] No key field(s) specified in attribute mapping. Falling back to using all mapped fields as key fields. Please go to attribute mapping and set one or more fields as key fields which can be used to find already existing elements.' All Pimcore Fields are already mapped. How to fix it?

  'Attributzuordnung' (2) tab in dataDirector for your dataport.

• Optionally, you can set this field as unique and mandatory in the class definition
