The creation of relationships with existing nodes requires explicit definition of twins in spreadsheet.

Hi all,

If one wants to add relationships to an existing graph through the Excel-import feature of the explorer, one gets an error message in case the spreadsheet defines a relationship with an existing node, not explicitly defined again in the spreadsheet. The error message is saying that the ID ‘xxx’ does not exist yet, while it is already present in the graph. The twin needs to be defined explicitly in the Excel-spreadsheet, after which the relationship can be created and the twin is not duplicated.

Kind regards,
Michiel


Start at the Excel-import feature in the explorer and reproduce the error with a spreadsheet relationship pointing to an existing graph node without redefining that node. Trace why the import reports the existing ID as missing, then verify that the relationship is created without duplicating the node.
